> USN-8818-1: Linux kernel vulnerabilities
[DATE: 24/09/2026 15:02]
[LANGUAGE: EN]
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so had been revoked, bypassing memory protections or escalating privileges.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;
- exFAT file system;
- Network file system (NFS) client;
- Network file system (NFS) server daemon;
- B.A.T.M.A.N. meshing protocol;
- IPv4 networking;
- IPv6 networking;
- Netfilter;
- RDS protocol;
