Summary

linux-aws-fips vulnerabilities

Details

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263)

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:

ARM64 architecture;
InfiniBand drivers;
Network drivers;
TCM subsystem;
B.A.T.M.A.N. meshing protocol;
HSR network protocol;
IPv4 networking;
IPv6 networking;
Netfilter;
RDS protocol; (CVE-2026-53131, CVE-2026-53186, CVE-2026-53216, CVE-2026-53221, CVE-2026-53354, CVE-2026-53355, CVE-2026-63886, CVE-2026-63887, CVE-2026-63888, CVE-2026-63912, CVE-2026-63922, CVE-2026-63924, CVE-2026-63984, CVE-2026-63992, CVE-2026-63993, CVE-2026-63994, CVE-2026-64000, CVE-2026-64007, CVE-2026-64091)
