| CVE-2026-7570 | 1 Quest | 1 Netvault Backup | 2026-06-25 | N/A |
| Quest NetVault Backup NVBUDashboard SQL Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest NetVault Backup. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the processing of NVBUDashboard JSON-RPC messages. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Was ZDI-CAN-27809. | ||||
| CVE-2026-53062 | 1 Linux | 1 Linux Kernel | 2026-06-25 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: dm cache policy smq: fix missing locks in invalidating cache blocks In passthrough mode, the policy invalidate_mapping operation is called simultaneously from multiple workers, thus it should be protected by a lock. Otherwise, we might end up with data races on the allocated blocks counter, or even use-after-free issues with internal data structures when doing concurrent writes. Note that the existing FIXME in smq_invalidate_mapping() doesn't affect passthrough mode since migration tasks don't exist there, but would need attention if supporting fast device shrinking via suspend/resume without target reloading. Reproduce steps: 1. Create a cache device consisting of 1024 cache entries dmsetup create cmeta --table "0 8192 linear /dev/sdc 0" dmsetup create cdata --table "0 131072 linear /dev/sdc 8192" dmsetup create corig --table "0 262144 linear /dev/sdc 262144" dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct dmsetup create cache --table "0 262144 cache /dev/mapper/cmeta \ /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0" 2. Populate the cache, and record the number of cached blocks fio --name=populate --filename=/dev/mapper/cache --rw=randwrite --bs=4k \ --size=64m --direct=1 nr_cached=$(dmsetup status cache | awk '{split($7, a, "/"); print a[1]}') 3. Reload the cache into passthrough mode dmsetup suspend cache dmsetup reload cache --table "0 262144 cache /dev/mapper/cmeta \ /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 passthrough smq 0" dmsetup resume cache 4. Write to the passthrough cache. By setting multiple jobs with I/O size equal to the cache block size, cache blocks are invalidated concurrently from different workers. fio --filename=/dev/mapper/cache --name=test --rw=randwrite --bs=64k \ --direct=1 --numjobs=2 --randrepeat=0 --size=64m 5. Check if demoted matches cached block count. These numbers should match but may differ due to the data race. nr_demoted=$(dmsetup status cache | awk '{print $12}') echo "$nr_cached, $nr_demoted" | ||||

| In the Linux kernel, the following vulnerability has been resolved: net/sched: cls_fw: fix NULL dereference of "old" filters before change() Like pointed out by Sashiko [1], since commit ed76f5edccc9 ("net: sched: protect filter_chain list with filter_chain_lock mutex") TC filters are added to a shared block and published to datapath before their ->change() function is called. This is a problem for cls_fw: an invalid filter created with the "old" method can still classify some packets before it is destroyed by the validation logic added by Xiang. Therefore, insisting with repeated runs of the following script: # ip link add dev crash0 type dummy # ip link set dev crash0 up # mausezahn crash0 -c 100000 -P 10 \ > -A 4.3.2.1 -B 1.2.3.4 -t udp "dp=1234" -q & # sleep 1 # tc qdisc add dev crash0 egress_block 1 clsact # tc filter add block 1 protocol ip prio 1 matchall \ > action skbedit mark 65536 continue # tc filter add block 1 protocol ip prio 2 fw # ip link del dev crash0 can still make fw_classify() hit the WARN_ON() in [2]: WARNING: ./include/net/pkt_cls.h:88 at fw_classify+0x244/0x250 [cls_fw], CPU#18: mausezahn/1399 Modules linked in: cls_fw(E) act_skbedit(E) CPU: 18 UID: 0 PID: 1399 Comm: mausezahn Tainted: G E 7.0.0-rc6-virtme #17 PREEMPT(full) Tainted: [E]=UNSIGNED_MODULE Hardware name: Red Hat KVM, BIOS 1.16.3-2.el9 04/01/2014 RIP: 0010:fw_classify+0x244/0x250 [cls_fw] Code: 5c 49 c7 45 00 00 00 00 00 41 5d 41 5e 41 5f 5d c3 cc cc cc cc 5b b8 ff ff ff ff 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc 90 <0f> 0b 90 eb a0 0f 1f 80 00 00 00 00 90 90 90 90 90 90 90 90 90 90 RSP: 0018:ffffd1b7026bf8a8 EFLAGS: 00010202 RAX: ffff8c5ac9c60800 RBX: ffff8c5ac99322c0 RCX: 0000000000000004 RDX: 0000000000000001 RSI: ffff8c5b74d7a000 RDI: ffff8c5ac8284f40 RBP: ffffd1b7026bf8d0 R08: 0000000000000000 R09: ffffd1b7026bf9b0 R10: 00000000ffffffff R11: 0000000000000000 R12: 0000000000010000 R13: ffffd1b7026bf930 R14: ffff8c5ac8284f40 R15: 0000000000000000 FS: 00007fca40c37740(0000) GS:ffff8c5b74d7a000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fca40e822a0 CR3: 0000000005ca0001 CR4: 0000000000172ef0 Call Trace: <TASK> tcf_classify+0x17d/0x5c0 tc_run+0x9d/0x150 __dev_queue_xmit+0x2ab/0x14d0 ip_finish_output2+0x340/0x8f0 ip_output+0xa4/0x250 raw_sendmsg+0x147d/0x14b0 __sys_sendto+0x1cc/0x1f0 __x64_sys_sendto+0x24/0x30 do_syscall_64+0x126/0xf80 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7fca40e822ba Code: d8 64 89 02 48 c7 c0 ff ff ff ff eb b8 0f 1f 00 f3 0f 1e fa 41 89 ca 64 8b 04 25 18 00 00 00 85 c0 75 15 b8 2c 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 7e c3 0f 1f 44 00 00 41 54 48 83 ec 30 44 89 RSP: 002b:00007ffc248a42c8 EFLAGS: 00000246 ORIG_RAX: 000000000000002c RAX: ffffffffffffffda RBX: 000055ef233289d0 RCX: 00007fca40e822ba RDX: 000000000000001e RSI: 000055ef23328c30 RDI: 0000000000000003 RBP: 000055ef233289d0 R08: 00007ffc248a42d0 R09: 0000000000000010 R10: 0000000000000000 R11: 0000000000000246 R12: 000000000000001e R13: 00000000000186a0 R14: 0000000000000000 R15: 00007fca41043000 </TASK> irq event stamp: 1045778 hardirqs last enabled at (1045784): [<ffffffff864ec042>] __up_console_sem+0x52/0x60 hardirqs last disabled at (1045789): [<ffffffff864ec027>] __up_console_sem+0x37/0x60 softirqs last enabled at (1045426): [<ffffffff874d48c7>] __alloc_skb+0x207/0x260 softirqs last disabled at (1045434): [<ffffffff874fe8f8>] __dev_queue_xmit+0x78/0x14d0 Then, because of the value in the packet's mark, dereference on 'q->handle' with NULL 'q' occurs: BUG: kernel NULL pointer dereference, address: 0000000000000038 [...] RIP: 0010:fw_classify+0x1fe/0x250 [cls_fw] [...] Skip "old-style" classification on shared blocks, so that the NULL dereference is fixed and WARN_ON() is not hit anymore in the short lifetime of invalid cls_fw "old-style" filters.

| CVE-2026-52808 | 1 Gogs | 1 Gogs | 2026-06-25 | 7.1 High |
| Gogs is an open source self-hosted Git service. Prior to 0.14.3, three API endpoints — PATCH /api/v1/repos/:owner/:repo/issue-tracker, PATCH /api/v1/repos/:owner/:repo/wiki, and POST /api/v1/repos/:owner/:repo/mirror-sync — are gated by reqRepoWriter() rather than reqRepoAdmin(). The equivalent operations in the web UI sit behind reqRepoAdmin, which requires AccessMode >= AccessModeAdmin. A write-level collaborator (who has AccessMode == AccessModeWrite < AccessModeAdmin) can therefore call these API endpoints directly to disable the native issue tracker or wiki, inject attacker-controlled external tracker/wiki URLs that redirect all repository visitors, or trigger mirror sync — none of which they are authorized to do. This vulnerability is fixed in 0.14.3. | ||||
| CVE-2026-52809 | 1 Gogs | 1 Gogs | 2026-06-25 | 6.8 Medium |
| Gogs is an open source self-hosted Git service. Prior to 0.14.3, password-reset tokens are generated using conf.Auth.ActivateCodeLives (the account-activation lifetime), not conf.Auth.ResetPasswordCodeLives. The token lifetime is baked into the token itself at generation time and is re-extracted from the token at verification time, making RESET_PASSWORD_CODE_LIVES irrelevant to actual enforcement. When an administrator configures a shorter reset window (e.g., 10 minutes) for compliance or security reasons, reset tokens remain exploitable for the full activation lifetime instead, while the reset email falsely advertises the shorter expiry. This vulnerability is fixed in 0.14.3. | ||||
| CVE-2026-52810 | 1 Gogs | 1 Gogs | 2026-06-25 | N/A |
| Gogs is an open source self-hosted Git service. Prior to 0.14.3, Git smart HTTP authorizes POST …/git-receive-pack using the client-supplied service query string (so ?service=git-upload-pack is evaluated as read access) while routing still runs git receive-pack, allowing push where only read should be allowed. This vulnerability is fixed in 0.14.3. | ||||
| CVE-2026-39897 | 1 Cacti | 1 Cacti | 2026-06-25 | N/A |
| Cacti is an open source performance and fault management framework. Versions 1.2.30 and below contain a Reflected XSS vulnerability in the html_auth_footer. This issue has been fixed in version 1.2.31. | ||||
| CVE-2026-39951 | 1 Cacti | 1 Cacti | 2026-06-25 | 7.6 High |

| CVE-2025-61664 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 4.9 Medium |
| A vulnerability in the GRUB2 bootloader has been identified in the normal module. This flaw, a memory Use After Free issue, occurs because the normal_exit command is not properly unregistered when its related module is unloaded. An attacker can exploit this condition by invoking the command after the module has been removed, causing the system to improperly access a previously freed memory location. This leads to a system crash or possible impacts in data confidentiality and integrity. | ||||
| CVE-2025-61663 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 4.9 Medium |
| A vulnerability has been identified in the GRUB2 bootloader's normal command that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the normal command is not properly unregistered when the module is unloaded. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability. Impact on the data integrity and confidentiality is also not discarded. | ||||
| CVE-2025-61662 | 2 Gnu, Redhat | 11 Grub2, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-06-25 | 7.8 High |
| A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded. | ||||
| CVE-2025-61661 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 4.8 Medium |
| A vulnerability has been identified in the GRUB (Grand Unified Bootloader) component. This flaw occurs because the bootloader mishandles string conversion when reading information from a USB device, allowing an attacker to exploit inconsistent length values. A local attacker can connect a maliciously configured USB device during the boot sequence to trigger this issue. A successful exploitation may lead GRUB to crash, leading to a Denial of Service. Data corruption may be also possible, although given the complexity of the exploit the impact is most likely limited. | ||||
| CVE-2025-59089 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 6 more | 2026-06-25 | 5.9 Medium |
| If an attacker causes kdcproxy to connect to an attacker-controlled KDC server (e.g. through server-side request forgery), they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copies the entire buffered stream into a new buffer on each recv() call, even when the transfer is incomplete, causing excessive memory allocation and CPU usage. Additionally, kdcproxy accepts incoming response chunks as long as the received data length is not exactly equal to the length indicated in the response header, even when individual chunks or the total buffer exceed the maximum length of a Kerberos message. This allows an attacker to send unbounded data until the connection timeout is reached (approximately 12 seconds), exhausting server memory or CPU resources. Multiple concurrent requests can cause accept queue overflow, denying service to legitimate clients. | ||||
| CVE-2025-54771 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 4.9 Medium |
| A use-after-free vulnerability has been identified in the GNU GRUB (Grand Unified Bootloader). The flaw occurs because the file-closing process incorrectly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded. | ||||
| CVE-2025-54770 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 4.9 Medium |
| A vulnerability has been identified in the GRUB2 bootloader's network module that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the net_set_vlan command is not properly unregistered when the network module is unloaded from memory. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability | ||||
| CVE-2025-6395 | 1 Redhat | 8 Ceph Storage, Discovery, Enterprise Linux and 5 more | 2026-06-25 | 6.5 Medium |
| A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). | ||||
| CVE-2025-6035 | 2 Gimp, Redhat | 3 Gimp, Enterprise Linux, Rhivos | 2026-06-25 | 6.1 Medium |
| A flaw was found in GIMP. An integer overflow vulnerability exists in the GIMP "Despeckle" plug-in. The issue occurs due to unchecked multiplication of image dimensions, such as width, height, and bytes-per-pixel (img_bpp), which can result in allocating insufficient memory and subsequently performing out-of-bounds writes. This issue could lead to heap corruption, a potential denial of service (DoS), or arbitrary code execution in certain scenarios. | ||||
| CVE-2025-6021 | 2 Redhat, Xmlsoft | 31 Discovery, Enterprise Linux, Enterprise Linux Eus and 28 more | 2026-06-25 | 7.5 High |
| A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input. | ||||
| CVE-2025-5987 | 2 Libssh, Redhat | 7 Libssh, Enterprise Linux, Enterprise Linux Eus and 4 more | 2026-06-25 | 8.1 High |
| A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with the SSH_OK code, resulting in libssh not properly detecting the error returned by the OpenSSL library. This issue can lead to undefined behavior, including compromised data confidentiality and integrity or crashes. | ||||
| CVE-2025-5962 | 1 Redhat | 2 Enterprise Linux, Rhivos | 2026-06-25 | 7.7 High |
| A flaw was found in the Lightspeed history service. Insufficient access controls allow a local, unprivileged user to access and manipulate the chat history of another user on the same system. By abusing inter-process communication calls to the history service, an attacker can view, delete, or inject arbitrary history entries, including misleading or malicious commands. This can be used to deceive another user into executing harmful actions, posing a risk of privilege misuse or unauthorized command execution through social engineering. | ||||
