> USN-8906-1: Linux kernel (IBM) vulnerabilities

[SOURCE] Ubuntu Security Notices [DATE: 08/10/2026 12:56] [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so had been revoked, bypassing memory protections or escalating privileges.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.
