CVE-2026-74860 1 Redhat 16 Cert Manager, Cost Management On Premise, Enterprise Linux and 13 more 2026-11-06 8.5 High
A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callback handler, where a string is freed twice. This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings.
CVE-2026-58016 2 Gnome, Redhat 25 Glib, Cert-manager Operator, Cert Manager and 22 more 2026-11-06 7.5 High
A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.
CVE-2026-96280 2 Flatpak, Redhat 8 Flatpak, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-11-06 7.5 High
The OCI delta stream parser read sizes as guint64 but passed them to GLib I/O and allocation functions expecting gsize (32 bits on 32-bit systems), causing undersized allocations while subsequent operations use the original 64-bit size, leading to heap buffer overflows. An attacker controlling an OCI registry can craft a delta stream that triggers this during flatpak install/update, potentially achieving code execution on 32-bit systems.
CVE-2026-55655 3 Openbsd, Openssh, Redhat 13 Openssh, Openssh, Enterprise Linux and 10 more 2026-11-05 5 Medium
A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session.
CVE-2026-55653 3 Openbsd, Openssh, Redhat 13 Openssh, Openssh, Enterprise Linux and 10 more 2026-11-05 4.3 Medium
A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS).
CVE-2026-53704 2 Gstreamer Project, Redhat 5 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-11-05 7.1 High
A flaw was found in GStreamer's RealMedia demuxer in the gst-plugins-ugly package. When processing a RealMedia file containing a specially crafted FILEINFO metadata section, the demuxer parses variable-name and variable-value pairs using re_skip_pascal_string() without validating that offsets remain within the mapped buffer. Additionally, the element count controlling the parsing loop is read from attacker-controlled data without validation, which can cause an infinite loop. A crafted RealMedia file can cause the application to crash, hang, or potentially read limited adjacent memory contents.
CVE-2026-53703 2 Gstreamer, Redhat 5 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-11-05 7.1 High
A vulnerability was found in the GStreamer RealMedia demuxer (gst-plugins-ugly). When processing a RealMedia (.rm) file, the demuxer parses MDPR (media properties) chunks to configure audio streams. For audio stream header versions 4 and 5, the parser reads fields such as codec type, packet size, sample rate, channel count, and extra codec data length from fixed offsets within the chunk without first checking that the chunk contains enough data. If a malicious file provides an MDPR chunk that is too small to contain a complete audio stream header, the parser reads beyond the end of the buffer. This can cause the application to crash. In some cases, bytes read past the buffer boundary may be incorporated into stream metadata, which could result in limited information disclosure.
CVE-2026-42014 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-05 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-2026-42015 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-11-05 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-2026-3833 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-05 6.5 Medium
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-52718 2 Gstreamer Project, Redhat 6 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-05 6.5 Medium
A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad. The gst_av1_parser_parse_tile_list_obu() function passes a byte count to a bit-reader API that expects a bit count, causing parser desynchronization. A remote attacker could trick a user into opening a specially crafted AV1 media file, triggering an assertion abort and causing the application to crash.
CVE-2026-50263 2 Redhat, X.org 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more 2026-11-05 5.5 Medium
A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure.
CVE-2026-50262 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-11-05 5.5 Medium
An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default.
CVE-2026-5119 2 Gnome, Redhat 9 Libsoup, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-05 5.9 Medium
A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or user impersonation.
CVE-2026-4948 2 Firewalld, Redhat 8 Firewalld, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-11-05 5.5 Medium
A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
CVE-2026-42169 2 Gimp, Redhat 6 Gimp, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-05 7.3 High
A heap-buffer-overflow vulnerability exists in the APNG (Animated PNG) file loader of GIMP. This flaw occurs when the `fcTL` width exceeds the `IHDR` width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to a BPP mismatch in the `load_layer()` function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution.
CVE-2026-4271 2 Gnome, Redhat 4 Libsoup, Enterprise Linux, Enterprise Linux Eus and 1 more 2026-11-05 5.3 Medium
A flaw was found in libsoup, a library for handling HTTP requests. This vulnerability, known as a Use-After-Free, occurs in the HTTP/2 server implementation. A remote attacker can exploit this by sending specially crafted HTTP/2 requests that cause authentication failures. This can lead to the application attempting to access memory that has already been freed, potentially causing application instability or crashes, resulting in a Denial of Service (DoS).
CVE-2026-43958 1 Redhat 5 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 2 more 2026-11-05 7.8 High
A flaw was found in rrdcached, a component of rrdtool. A local attacker with access to a rrdcached socket can exploit a stack-based buffer overflow by sending an oversized CREATE request. This vulnerability can lead to a denial of service by crashing the daemon or potentially allow for arbitrary code execution, impacting the integrity and confidentiality of data.
CVE-2026-42013 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-05 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42011 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-11-05 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
