| CVE-2026-9797 | 2 Red Hat, Redhat | 3 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak | 2026-11-06 | 6.5 Medium |
| A flaw was found in Keycloak's administrative services (org.keycloak.services.resources.admin). A highly privileged attacker, authenticated with a 'manage-clients' role, could exploit this vulnerability through several methods, including manipulating client JSON Web Key Sets (JWKS), swapping client authenticator types and resetting secrets, or downloading legitimate signing keys. Successful exploitation allows the attacker to obtain a token with 'realm-admin' role assignments, leading to privilege escalation and potential unauthorized access to sensitive resources. | ||||
| CVE-2026-114691 | 3 Gcc, Red Hat, Redhat | 9 Gcc, Enterprise Linux, Enterprise Linux and 6 more | 2026-11-06 | 5.9 Medium |
| A flaw was found in the libstdc++ component of GCC. An attacker who can provide an excessively large element count to a boolean vector (std::vector<bool>) constructor can trigger an integer wrap during internal memory calculations. This issue leaves the container in an inconsistent state, leading to out-of-bounds memory access and resulting in an application crash or a Denial of Service (DoS) during subsequent operations. | ||||
| CVE-2026-114690 | 3 Gcc, Red Hat, Redhat | 9 Gcc, Enterprise Linux, Enterprise Linux and 6 more | 2026-11-06 | 6.2 Medium |
| A flaw was found in GCC. An out-of-bounds memory access vulnerability exists in the libstdc++ parallel search implementation due to an undersized internal buffer. A local attacker can exploit this flaw by providing crafted search data to an application compiled with parallel mode, causing the process to crash and leading to a Denial of Service (DoS). | ||||
| CVE-2026-107161 | 2 Cyrusimap, Redhat | 8 Cyrus-sasl, Enterprise Linux, Hardened Images and 5 more | 2026-11-06 | 7.5 High |
| A heap-based buffer overflow flaw was found in Cyrus SASL. The add_to_challenge() function in the DIGEST-MD5 plugin computes the size of the buffer needed for a challenge/response field before DIGEST-MD5 quoting is applied, but does not recompute that size when quoting (escaping special characters) makes the value longer. The under-sized buffer is then passed to strcat(), causing a heap-based out-of-bounds write whose size depends on attacker-controlled input. A malicious or on-path DIGEST-MD5 (or HTTP Digest) server can trigger this flaw in a connecting client by supplying a crafted challenge field, such as realm or nonce, most likely resulting in a crash of the client application. | ||||
| CVE-2026-103242 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Openshift Ai and 1 more | 2026-11-06 | 7.1 High |
| A heap-based buffer overflow flaw was found in rpm. RPMTAG_FILESIGNATURES in a crafted, unsigned RPM package's main header is declared with the wrong header type, causing hex2binv() to allocate a one-byte buffer and then write the tag's attacker-controlled, hex-decoded content — of attacker-chosen length — past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package. | ||||
| CVE-2026-15588 | 1 Redhat | 18 Ai Inference Server, Cert Manager, Discovery and 15 more | 2026-11-06 | 5.3 Medium |
| A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang. | ||||
| CVE-2026-15028 | 1 Redhat | 6 Cost Management On Premise, Enterprise Linux, Hummingbird and 3 more | 2026-11-06 | 3.9 Low |
| A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system. | ||||
| CVE-2026-15003 | 2 Gnu, Redhat | 8 Binutils, Enterprise Linux, Hardened Images and 5 more | 2026-11-06 | 5.6 Medium |
| A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing. | ||||
| CVE-2026-14164 | 3 Libarchive, Red Hat, Redhat | 16 Libarchive, Enterprise Linux, Ai Inference Server and 13 more | 2026-11-06 | 7.5 High |
| A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service. | ||||
| CVE-2026-13757 | 2 P11-kit Project, Redhat | 13 P11-kit, Cert Manager, Cost Management and 10 more | 2026-11-06 | 6.2 Medium |
| A flaw was found in p11-kit. The RPC message attribute parsing functions p11_rpc_message_get_attribute() and p11_rpc_message_get_attribute_array_value() form a mutually-recursive call chain with no recursion depth limit when processing nested CKA_WRAP_TEMPLATE, CKA_UNWRAP_TEMPLATE, and CKA_DERIVE_TEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services. | ||||
| CVE-2026-13595 | 3 Kernel, Linux, Redhat | 10 Util-linux, Util-linux, Cost Management On Premise and 7 more | 2026-11-06 | 6.8 Medium |
| A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service. | ||||
| CVE-2026-12610 | 3 Fedoraproject, Redhat, Sssd | 9 Sssd, Enterprise Linux, Hardened Images and 6 more | 2026-11-06 | 6.4 Medium |
| A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that disrupts authentication. This vulnerability also presents a potential for privilege escalation, although it is difficult to exploit. | ||||
| CVE-2026-11850 | 1 Redhat | 7 Enterprise Linux, Hardened Images, Hummingbird and 4 more | 2026-11-06 | 5 Medium |
| An integer underflow vulnerability was found in MIT krb5 in the berval2tl_data() function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c. The function performs an unsigned subtraction (bv_len - 2) without a prior bounds check. When bv_len is 0 or 1, the subtraction wraps to a large value which is then truncated to uint16_t, yielding 0xFFFE (65534) or 0xFFFF (65535). The subsequent malloc succeeds and memcpy reads up to 65534 bytes from a 0-1 byte buffer, resulting in a heap out-of-bounds read. The attack vector involves a malicious or compromised LDAP KDB backend returning a krbExtraData attribute with bv_len < 2, triggering the underflow when the KDC or kadmind reads principal data. | ||||
| CVE-2025-25208 | 1 Redhat | 2 Connectivity Link, Openshift Ai | 2026-11-06 | 5.7 Medium |
| A Developer persona can bring down the Authorino service, preventing the evaluation of all AuthPolicies on the cluster | ||||
| CVE-2025-25207 | 1 Redhat | 2 Connectivity Link, Openshift Ai | 2026-11-06 | 5.7 Medium |
| The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks. | ||||
| CVE-2025-5278 | 1 Redhat | 10 Cert Manager, Cost Management, Discovery and 7 more | 2026-11-06 | 4.4 Medium |
| A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data. | ||||
| CVE-2026-95521 | 2 Redhat, Rpm | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-11-06 | 7.8 High |
| A command injection flaw was found in rpm. Installing or rebuilding a source RPM whose source or spec file basenames contain a %() macro construct causes rpm to execute an attacker-controlled shell command via popen() while relocating the source file list. This allows arbitrary command execution as the invoking (typically non-root) user, simply by installing, rebuilding, or otherwise processing an untrusted .src.rpm. | ||||
| CVE-2026-95619 | 1 Redhat | 7 Enterprise Linux, Hardened Images, Hummingbird and 4 more | 2026-11-06 | 7.7 High |
| A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability. | ||||
| CVE-2026-95520 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Openshift Ai and 1 more | 2026-11-06 | 7.1 High |
| A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package. | ||||
| CVE-2026-95519 | 2 Redhat, Rpm | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-11-06 | 7.8 High |
| A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using `rpm -q -p` or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the `rpm` process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account. | ||||
