The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8279-1 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:

    - Cryptographic API;

    - Ethernet bonding driver;

    - SMB network file system;

    - Netfilter;

    - io_uring subsystem;

    - Packet sockets;

    - TLS protocol; (CVE-2024-35862, CVE-2024-50060, CVE-2026-23274, CVE-2026-23351, CVE-2026-31419,     CVE-2026-31504, CVE-2026-31533, CVE-2026-43033, CVE-2026-43077, CVE-2026-43078)
