CVE-2026-18078 1 Ibm 1 I 2026-09-08 4.3 Medium
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to cause a denial of service due to an integer overflow.
CVE-2026-86143 1 Xmlsoft 1 Libxml2 2026-09-08 6.9 Medium
In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a callback.
CVE-2026-62886 1 Microsoft 7 .net, .net Framework, Microsoft Visual Studio 2022 and 4 more 2026-09-08 7.8 High
Integer overflow or wraparound in .NET allows an unauthorized attacker to elevate privileges locally.
CVE-2026-86314 1 Samsung Open Source 1 Walrus 2026-09-08 6.2 Medium
Integer overflow in the source-bounds check in Memory::init() (src/runtime/Memory.cpp) in Samsung walrus on all platforms allows a remote attacker to cause an out-of-bounds heap read and denial of service via a crafted WebAssembly module in which a 32-bit unsigned addition wraps around and bypasses the bounds check. This issue affects Walrus: ff3bf5ff5c4878f8e5572c9593d303f6bc997443.
CVE-2026-84732 1 Openvpn 1 Openvpn 2026-09-08 7.5 High
Retransmissions of ACK packet ID in OpenVPN through 2.6.22 and 2.7.6 allow remote unauthenticated attackers to cause a denial of service via crafted inputs that trigger a timeout integer overflow
CVE-2022-50998 2 Nokogiri, Sparklemotion 2 Nokogiri, Nokogiri 2026-09-08 7.5 High
This CVE ID has been rejected as a duplicate.
CVE-2026-18445 1 Ni 1 Labview 2026-09-08 6.6 Medium
There is an integer overflow vulnerability resulting in an out-of-bounds write recently discovered in NI LabVIEW.  This may result in information disclosure or arbitrary code execution.  Successful exploitation requires an attacker to get a user to open a specially crafted VI file.  This vulnerability affects NI LabVIEW 2026 Q3 and prior versions.
CVE-2026-86139 1 Xmlsoft 1 Libxml2 2026-09-08 6.9 Medium

Integer Overflow or Wraparound vulnerability in Cesanta Mongoose Web Server v7.14 allows an attacker to send an unexpected TLS packet and produce a segmentation fault on the application.
CVE-2026-80887 1 Linux 1 Linux Kernel 2026-09-04 N/A
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: use check_add_overflow for shader size+offset bound vmw_shader_define() validates the user-supplied shader window against its backing buffer with (u64)buffer->tbo.base.size < (u64)size + (u64)offset drm_vmw_shader_create_arg::offset is __u64 in the uapi; when it is near U64_MAX the unsigned addition wraps and the resulting tiny value passes the check. The unbounded offset is then stored in res->guest_memory_offset and forwarded to host SVGA shader-create commands. Use check_add_overflow() to detect the wrap and compare the resulting endpoint against the buffer size.
CVE-2026-55400 1 Absolute 1 Secure Access 2026-09-04 6.5 Medium
CVE-2026-55400 is an integer underflow in Secure Access servers prior to version 14.57. Attackers with an authenticated session can send specially crafted traffic to a server in a non-default configuration and cause a persistent denial of service.
CVE-2026-80908 1 Linux 1 Linux Kernel 2026-09-04 N/A
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Reject UVD message with dimensions above 4096 Fixes potential overflow in DPB size calculations. (cherry picked from commit 05e1387d151f71569fbe122d2c89f9db0c21dc10)
CVE-2026-80909 1 Linux 1 Linux Kernel 2026-09-04 N/A
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Reject UVD message with invalid number of h265 refs Same change as for h264, avoids overflow later when calculating min dpb size. (cherry picked from commit a4b0720e4f1601f97f59a2be9c1b4b94fa6527d5)
CVE-2026-47857 2 Broadcom, Spring 2 Reactor Core, Reactor Core 2026-09-04 5.9 Medium
In Reactor Core, applications that use the Flux.windowTimeout operator with fairBackpressure enabled are vulnerable to a Denial of Service (DoS) condition. Reactor Core 3.8.0 - 3.8.6 Reactor Core 3.5.0 - 3.7.19 Reactor Core 3.4.41 and earlier
CVE-2026-69419 1 Microsoft 1 Azure Data Manager For Energy 2026-09-04 8.5 High
Integer overflow or wraparound in Azure Data Manager for Energy allows an authorized attacker to execute code over a network.
CVE-2026-64357 1 Linux 1 Linux Kernel 2026-09-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchmaps reservation limit check xfs_exchmaps_estimate_overhead() adds the bmbt and rmapbt overhead to a local resblks variable, but the final UINT_MAX check still tests req->resblks. That is the reservation value from before the overhead was added. The computed value is stored back in req->resblks and later passed to xfs_trans_alloc(), whose block reservation argument is unsigned int. Check the computed reservation so the existing limit applies to the value that will be used.
CVE-2026-71223 1 Redhat 1 Gfs2-utils 2026-09-04 7.0 High
An integer overflow vulnerability was found in gfs2-utils. The resource group allocation size computation on 32-bit platforms causes an undersized buffer allocation followed by heap out-of-bounds writes when processing crafted GFS2 filesystem images. This vulnerability does not affect 64-bit builds.
CVE-2026-53059 1 Linux 1 Linux Kernel 2026-09-04 7.8 High
In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to region_count overflow The local variable region_count in create_log_context() is declared as unsigned int (32-bit), but dm_sector_div_up() returns sector_t (64-bit). When a device-mapper target has a sufficiently large ti->len with a small region_size, the division result can exceed UINT_MAX. The truncated value is then used to calculate bitset_size, causing clean_bits, sync_bits, and recovering_bits to be allocated far smaller than needed for the actual number of regions. Subsequent log operations (log_set_bit, log_clear_bit, log_test_bit) use region indices derived from the full untruncated region space, causing out-of-bounds writes to kernel heap memory allocated by vmalloc. This can be reproduced by creating a mirror target whose region_count overflows 32 bits: dmsetup create bigzero --table '0 8589934594 zero' dmsetup create mymirror --table '0 8589934594 mirror \ core 2 2 nosync 2 /dev/mapper/bigzero 0 \ /dev/mapper/bigzero 0' The status output confirms the truncation (sync_count=1 instead of 4294967297, because 0x100000001 was truncated to 1): $ dmsetup status mymirror 0 8589934594 mirror 2 254:1 254:1 1/4294967297 ... This leads to a kernel crash in core_in_sync: BUG: scheduling while atomic: (udev-worker)/9150/0x00000000 RIP: 0010:core_in_sync+0x14/0x30 [dm_log] CR2: 0000000000000008 Fixing recursive fault but reboot is needed! Fix by widening the local region_count to sector_t and adding an explicit overflow check before the value is assigned to lc->region_count.
CVE-2026-84141 1 Mozilla 2 Firefox, Thunderbird 2026-09-03 9.8 Critical
Integer overflow in the Graphics: ImageLib component. This vulnerability was fixed in Firefox 155, Firefox ESR 153.2, Thunderbird 155, and Thunderbird 153.2.
CVE-2026-48486 1 Signum-network 1 Signum-node 2026-09-03 7.5 High
Signum Node is a HDD-mined cryptocurrency using an energy efficient and fair Proof-of-Commitment (PoC+) consensus algorithm. Prior to version 3.9.9, an integer overflow in BlockServiceImpl.applyBlock() allowed a miner to receive an arbitrarily inflated block reward by crafting a block with a negative totalFeeCashBackNqt value. The vulnerability was introduced when the SMART_FEES hardfork (block ~1,029,000) enabled fee cash-back and burn accounting without overflow protection. This issue has been patched in version 3.9.9.
