Ubuntu 24.04 LTS / 25.10 : Linux kernel (Azure) vulnerabilities (USN-8310-1)

high Nessus Plugin ID 317095

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8310-1 advisory.

 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:

 - S390 architecture;

 - Cryptographic API;

 - GPU drivers;

 - Ethernet bonding driver;

 - Microsoft Azure Network Adapter (MANA) driver;

 - Network file system (NFS) server daemon;

 - Distributed Switch Architecture;

 - Netfilter;

 - Control group (cgroup);

 - Kernel kexec() syscall;

 - Memory management;

 - MAC80211 subsystem;

 - Multipath TCP;

 - Packet sockets;

 - TLS protocol;

 - Unix domain sockets; (CVE-2025-71088, CVE-2025-71090, CVE-2025-71127, CVE-2025-71134, CVE-2025-71139, CVE-2025-71141, CVE-2025-71142, CVE-2025-71144, CVE-2025-71152, CVE-2025-71155, CVE-2026-23274, CVE-2026-23351, CVE-2026-23394, CVE-2026-23454, CVE-2026-31419, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033, CVE-2026-43077, CVE-2026-43078, CVE-2026-43276)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
