The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8635-1 advisory.

    Siebe Devroe, Hlose Gollier, and Mathy Vanhoef discovered that the WiFi implementation in the Linux     kernel did not properly handle aggregated frames in mesh networks, due to an incorrect fix for     CVE-2020-24588. A physically proximate attacker could use this issue to inject packets. (CVE-2025-27558)

    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)

    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:
