CVE-2026-85234 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-11 7.5 High
A flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.
CVE-2026-91205 1 Redhat 1 Enterprise Linux 2026-11-11 6 Medium
A flaw was found in cockpit-files. A local unprivileged attacker can exploit a race condition during directory creation with owner assignment. By controlling a writable parent directory, the attacker can replace a newly created directory with a symbolic link (symlink) before the ownership change operation (chown) is applied. This allows the attacker to redirect the ownership change to an arbitrary file, potentially leading to information disclosure or unauthorized modification of sensitive files.
CVE-2026-91202 1 Redhat 1 Enterprise Linux 2026-11-11 6.1 Medium
A flaw was found in cockpit-files. A low-privileged local user can exploit this vulnerability by crafting a directory containing a symbolic link (symlink) and then using the privileged "Paste as owner" function. This allows for arbitrary file ownership changes outside the intended pasted directory, leading to a compromise of data integrity. In some cases, this could also lead to reduced confidentiality if the new ownership grants unauthorized read access. Exploitation requires user interaction to select a non-original owner during the paste operation.
CVE-2026-94184 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-11 5.3 Medium
A stack-based buffer overflow flaw was found in fetchmail when built with NTLM support. A malicious or compromised mail server advertising NTLM authentication can send a crafted Type 2 challenge that causes fetchmail to write past a fixed stack buffer while building the NTLM authenticate response. This may lead to remote code execution depending on stack-frame layout, or to authentication failure or process termination under memory hardening.
CVE-2026-87853 2 Redhat, Sssd 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more 2026-11-11 7.5 High
A flaw was found in SSSD's IdP authentication provider. The eval_access_token_buf() function compares the OIDC subject identifier using strncmp() with the authenticated user's identifier length, performing a prefix comparison instead of an exact match. An attacker whose IdP identifier is a strict prefix of a target user's identifier can authenticate as the target user.
CVE-2026-16118 1 Redhat 11 Ai Inference Server, Cert Manager, Cost Management On Premise and 8 more 2026-11-11 7.1 High
A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption.
CVE-2026-15711 2 Libsoup, Redhat 9 Libsoup, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-11 7.5 High
A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames (e.g., PING, PONG, CLOSE) contain a payload of 125 bytes or less. A remote, unauthenticated attacker can exploit this by sending a non-compliant, oversized control frame. Because the parser handles this protocol violation improperly instead of throwing an immediate connection termination error, it triggers a internal processing crash, resulting in a remote denial of service (DoS) for applications utilizing libsoup WebSockets.
CVE-2026-15709 2 Libsoup, Redhat 9 Libsoup, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-11 7.5 High
A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop (inflate()) processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via max_incoming_payload_size, it fails to track or limit memory allocation during decompression. A separate check for decompressed size (max_total_message_size) exists but executes only after inflation is complete, and it is entirely disabled by default for client connections. A remote, unauthenticated attacker can exploit this by sending a small, highly compressed payload (a decompression bomb), causing unbounded memory allocation that triggers an Out-of-Memory (OOM) crash and a Denial of Service (DoS).
CVE-2026-125767 2026-11-11 5.3 Medium
Insertion of Sensitive Information Into Sent Data vulnerability in NerdPress Hubbub Lite social-pug allows Retrieve Embedded Sensitive Data.This issue affects Hubbub Lite: from n/a through 1.36.3.1.
CVE-2026-96442 2 Gnu, Redhat 3 Emacs, Enterprise Linux, Rhel Els 2026-11-11 7.8 High
A code execution flaw was found in Emacs, affecting versions prior to 31.2. The Flymake mode using language backends other than Lisp would execute arbitrary code from the edited file while performing syntax checking. Viewing or editing untrusted files using Emacs could lead to arbitrary code execution with the privileges of the user running Emacs.
CVE-2026-79992 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-11 7.8 High
A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution.
CVE-2026-96889 1 Redhat 10 Enterprise Linux, Enterprise Linux Ai, Enterprise Linux Eus and 7 more 2026-11-11 7.8 High
A flaw was found in librsvg. When processing an SVG document containing nested XML inclusions (Xincludes) with duplicate entity declarations, a use-after-free error can occur. This vulnerability arises because the library incorrectly frees an XML entity that is still in use by the parser. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code.
CVE-2026-84042 2 Containers, Redhat 5 Crun, Enterprise Linux, Hardened Images and 2 more 2026-11-11 7.8 High
A flaw was found in crun. When crun is built with libkrun and a container is started rootful with passt networking (krun.use_passt), crun can execute attacker-controlled payload from the container image with host root privileges. The issue is a regression in crun 1.29. It affects crun >= 1.29
CVE-2026-78002 2 Redhat, Rsyslog 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more 2026-11-11 7.5 High
A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript `replace()` function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory corruption. Successful exploitation can lead to a denial of service (DoS) for the affected system.
CVE-2026-102560 3 Gnome, Libsoup, Redhat 7 Libsoup, Libsoup, Enterprise Linux and 4 more 2026-11-11 8.6 High
A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.
CVE-2026-102559 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-11 8.6 High
A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow.
CVE-2026-102558 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-11 8.6 High
A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data.
CVE-2026-102557 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-11 8.6 High
A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used the full length, leading to heap corruption or a crash.
CVE-2026-102556 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-11 8.6 High
A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap corruption or a crash upon receiving a crafted Pong.
CVE-2026-102555 3 Gnome, Libsoup, Redhat 5 Libsoup, Libsoup, Enterprise Linux and 2 more 2026-11-11 8.2 High
A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.
