> USN-8715-2: Linux kernel (AWS FIPS) vulnerabilities

[SOURCE] Ubuntu Security Notices [DATE: 18/09/2026 08:38] [LANGUAGE: EN]

Siebe Devroe, Héloïse 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)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
