Ubuntu Security Advisories
3 days 3 hours ago
It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-31431) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Cryptographic API; - Packet sockets; (CVE-2026-31504, CVE-2026-43033, CVE-2026-43077, CVE-2026-43078, CVE-2026-46028)

USN-8440-1: Linux kernel (Azure) vulnerabilities

Ubuntu Security Advisories
3 days 15 hours ago
Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A privileged attacker could possibly use this issue to cause load malicious CPU microcode causing loss of integrity and confidentiality. (CVE-2024-36347) It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-31431) It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998, CVE-2026-46000) It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-43503, CVE-2026-46300) Qualys discovered that a race condition existed in the ptrace subsystem of the Linux kernel when privileged processes are exiting. An unprivileged local attacker could use this issue to expose sensitive information. (CVE-2026-46333) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a memory leak when handling AppArmor notifications. A local attacker could use this to cause resource exhaustion. (CVE-2026-47326) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a NULL pointer dereference when handling AppArmor notifications. A local attacker could use this to cause a kernel oops. (CVE-2026-47327) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an invalid free when handling AppArmor notifications. A local attacker could use this to corrupt kernel memory. (CVE-2026-47328) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained insufficient validation of AppArmor notification responses. A local attacker could use this to allow crafted responses to be processed. (CVE-2026-47329) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 used an uninitialized variable when handling AppArmor notifications. A local attacker could use this to cause incorrect caching of data. (CVE-2026-47330) Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a use- after-free (UAF) bug. A local attacker could use this to cause memory corruption and, theoretically, arbitrary code execution. (CVE-2026-47331) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an out-of-bounds (OOB) read when handling AppArmor notifications. A local attacker could use this to cause information disclosure of kernel memory. (CVE-2026-47332) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a out-of-bounds (OOB) read when handling AppArmor notifications. A local attacker could use this to cause kernel memory corruption and, theoretically, influence processing of AppArmor policies. (CVE-2026-47333) Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained incorrect holding of locks when handling AppArmor notifications. A local attacker could use this to cause a kernel panic or deadlock. (CVE-2026-47334) Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a NULL pointer dereference when handling AppArmor notifications. A local attacker could use this to cause a kernel panic. (CVE-2026-47335) Tristan Madani discovered that Ubuntu Linux kernel 6.8 used an uninitialized variable when handling AppArmor AF_INET/AF_INET6 socket mediation. A local attacker could use this to influence processing of fine- grained network socket mediation. (CVE-2026-47336) Tristan Madani and Trevor Lawrence have each independently discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a NULL pointer dereference when handling AppArmor network socket mediation. A local attacker could use this to cause a kernel oops. (CVE-2026-47337) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

(CVE-2026-43906) It was discovered that OpenImageIO contained multiple integer overflow vulnerabilities when processing DPX files. An attacker could possibly use these issues to cause a denial of service or execute arbitrary code. (CVE-2026-43907, CVE-2026-43908, CVE-2026-43909)

Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-2640) Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-32629) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

FEDORA-EPEL-2026-f33139a01c Packages in this update:
  • coturn-4.13.1-1.el10_2
Update description: Coturn 4.13.1 What's in this release
  • Security fixes
What's Changed
  • Null-terminate server_name in stun_is_challenge_response_str
  • Canonicalize all IPv4-in-IPv6 encodings before peer-IP checks
  • Auto-deny coturn's own database backend endpoints as relay peers
  • Deny link-local / ULA / site-local relay peers by default
Coturn 4.13.0 What's in this release
  • More performance improvements for --udp-recvmmsg and --multiplex-peer. If your system does not rely on TURN unique ports give multiplexing a try - it has capacity to dramatically increase performance.
  • Security fixes
What's Changed
  • Wrap atomic everywhere
  • Fix sendmmsg stride bug in multiplex-peer UDP batch flush
  • Reap TURN permissions/channels via a per-thread sweep instead of per-object timers
  • Add --udp-sendmmsg-log to observe egress sendmmsg/UDP-GSO batching
  • Expose recvmmsg/sendmmsg UDP batch sizes as Prometheus metrics
  • Restrict recvmmsg fast path to shared fan-in sockets (make --udp-recvmmsg useful standalone)
  • Enable --udp-recvmmsg by default on Linux
  • Security hardening: port parsing, admin brute-force throttle, credential log redaction, constant-time compare, OAuth bounds checks, permission cap
  • Add continuous latency mode to stunclient
  • Fix test_redis_format link failure
  • Fix configure MANPREFIX typo
  • Fix missing sqlite3 dependendcy
  • Fix UDP receive buffer ownership

USN-8437-1: rabbitmq-c vulnerabilities

Ubuntu Security Advisories
3 days 23 hours ago
It was discovered that rabbitmq-c exposed credentials in command-line arguments under certain circumstances. A local attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2023-35789) It was discovered that rabbitmq-c incorrectly handled AMQP frame lengths under certain circumstances, which could lead to an out-of-bounds read. A remote attacker could possibly use this issue to cause rabbitmq-c to crash, resulting in a denial of service. (CVE-2026-44235) It was discovered that rabbitmq-c incorrectly handled AMQP login handshakes under certain circumstances, which could lead to a heap buffer overflow. A remote attacker could possibly use this issue to cause rabbitmq-c to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-44236)
