CVE-2026-92824 2 Red Hat, Redhat 6 Enterprise Linux, Enterprise Linux, Hardened Images and 3 more 2026-11-04 6.2 Medium
A flaw was found in libmodulemd. In the module stream v2 rpm-map emission path, an inner loop incorrectly uses the count of digest algorithms as its bound instead of the number of checksums in the current digest table. Crafted modulemd v2 metadata with multiple digest types can trigger an out-of-bounds read during YAML serialization, typically causing a crash and resulting in a denial of service.
CVE-2026-12610 3 Fedoraproject, Redhat, Sssd 7 Sssd, Enterprise Linux, Hardened Images and 4 more 2026-11-04 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-2026-115455 3 Gcc, Red Hat, Redhat 7 Gcc, Enterprise Linux, Enterprise Linux and 4 more 2026-11-04 6.5 Medium
A flaw was found in GCC libstdc++. When an application extracts data into a bitset from a wide-character stream, internal stack memory allocation fails to properly account for character size and alignment. An attacker capable of supplying crafted input to an affected application could trigger a stack-based buffer overflow leading denial of service (DoS).
CVE-2026-2625 3 Redhat, Rust-rpm-sequoia, Sequoia-pgp 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-11-04 4 Medium
A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification.
CVE-2026-111497 17 7-zip, Andybalholm, Anthropic and 14 more 28 P7zip, Brotli, Bun and 25 more 2026-11-03 9.8 Critical
A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream. Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1.
CVE-2026-5419 2 Gnu, Redhat 13 Gnutls, Cert Manager, Discovery and 10 more 2026-11-03 3.7 Low
A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure.
CVE-2026-42015 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-11-03 5.3 Medium
A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts.
CVE-2026-42014 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-03 6.6 Medium
A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.
CVE-2026-42012 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-03 7.1 High
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.
CVE-2025-9566 1 Redhat 9 Enterprise Linux, Hummingbird, Openshift and 6 more 2026-11-03 8.1 High
There's a vulnerability in podman where an attacker may use the kube play command to overwrite host files when the kube file container a Secrete or a ConfigMap volume mount and such volume contains a symbolic link to a host file path. In a successful attack, the attacker can only control the target file to be overwritten but not the content to be written into the file. Binary-Affected: podman Upstream-version-introduced: v4.0.0 Upstream-version-fixed: v5.6.1
CVE-2026-16517 2 Libarchive, Redhat 6 Libarchive, Enterprise Linux, Hardened Images and 3 more 2026-11-02 2.9 Low
A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.
CVE-2026-15028 1 Redhat 4 Cost Management On Premise, Enterprise Linux, Hummingbird and 1 more 2026-11-02 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-2026-11605 2 Isc, Redhat 3 Bind, Bind 9, Hummingbird 2026-11-02 7.5 High
The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to waste disproportionate CPU time. This issue affects BIND 9 versions 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, and 9.20.9-S1 through 9.20.24-S1.
CVE-2026-109619 4 Paloaltonetworks, Php, Redhat and 1 more 24 Pan-os, Panorama M-200, Panorama M-300 and 21 more 2026-11-02 8.1 High
PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE).
CVE-2026-109618 4 Paloaltonetworks, Php, Redhat and 1 more 23 Pan-os, Panorama M-200, Panorama M-300 and 20 more 2026-11-02 9.8 Critical
PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the request. Some contexts may not properly account for this scenario and leave request memory in an uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote code execution (RCE).
CVE-2026-115456 3 Gcc, Red Hat, Redhat 7 Gcc, Enterprise Linux, Enterprise Linux and 4 more 2026-11-02 3.7 Low
A flaw was found in gcc. An attacker could cause a Denial of Service (DoS) by passing a string that is not null-terminated to the std::from_chars() function in the libstdc++ library. This issue triggers an out-of-bounds read beyond the allocated buffer, potentially leading to invalid data parsing or an application crash.
CVE-2026-72693 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-11-02 7.8 High
`openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat("/proc/<pid>/fd/0")`. `stat()` on `/proc/<pid>/fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path.
CVE-2026-86469 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-11-02 5.3 Medium
A flaw was found in GLib2. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the destination directory can win that race and redirect the write to another file.
