CVE-2026-81665 2 Corosync, Redhat 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more 2026-11-02 7.5 High
A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.
CVE-2026-74860 1 Redhat 16 Cert Manager, Cost Management On Premise, Enterprise Linux and 13 more 2026-11-02 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-2026-102559 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-02 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 2026-11-02 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 2026-11-02 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 2026-11-02 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-2026-76561 1 Redhat 6 Certificate System, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-02 7.2 High
A flaw was found in Dogtag PKI, as used by FreeIPA's certificate authority component. The certificate profile import functionality does not fully validate uploaded profile content beyond the profile ID. An authenticated user with CA Administrator privileges can exploit Dogtag's ExternalProcessConstraint mechanism to execute arbitrary commands with attacker-controlled environment variables, achieving code execution as the pkiuser account.
CVE-2026-96280 2 Flatpak, Redhat 5 Flatpak, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-11-02 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-2026-96275 2 Flatpak, Redhat 5 Flatpak, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-11-02 8.8 High
A malicious or compromised Flatpak repository can write attacker-controlled content to arbitrary locations on the host filesystem via extract_extra_data(). On system installs, the write happens as root. Two issues combine: `files/extra` is resolved via path operations that follow symlinks, and blob names from `xa.extra-data-sources` are not sanitized against `..` traversal.
CVE-2026-42169 2 Gimp, Redhat 5 Gimp, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-11-02 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-2026-58379 2 Gimp, Redhat 6 Gimp, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-02 7.3 High
A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.
CVE-2026-102560 3 Gnome, Libsoup, Redhat 6 Libsoup, Libsoup, Enterprise Linux and 3 more 2026-11-02 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-2026-102555 3 Gnome, Libsoup, Redhat 4 Libsoup, Libsoup, Enterprise Linux and 1 more 2026-11-02 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.
CVE-2026-71226 2 Redhat, Smuellerdd 10 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 7 more 2026-11-02 7.3 High
Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers.
CVE-2026-71225 2 Redhat, Smuellerdd 8 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 5 more 2026-11-02 6.5 Medium
A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs (over 64 KiB) in stateful modes such as Counter (CTR) or Cipher Block Chaining (CBC), the library improperly reuses the Initialization Vector (IV) for each internal data chunk. A remote attacker could potentially exploit this by making an application that uses libkcapi process specially crafted large inputs. This can lead to a significant weakening of data confidentiality, as the repeated IV use can expose relationships in encrypted plaintext, and may also affect data integrity by causing incorrect cryptographic processing.
CVE-2026-71227 2 Redhat, Smuellerdd 8 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 5 more 2026-11-02 5.1 Medium
A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive.
CVE-2025-6170 2 Redhat, Xmlsoft 19 Ai Inference Server, Cert Manager, Discovery and 16 more 2026-11-02 2.5 Low
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2026-79678 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Freeipa and 5 more 2026-11-02 8.1 High
A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion.
CVE-2026-76578 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more 2026-11-02 9.8 Critical
A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.
CVE-2026-73198 2 Freeipa, Redhat 8 Freeipa, Enterprise Linux, Enterprise Linux Eus and 5 more 2026-11-02 7.5 High
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.
