USN-8727-1: Linux kernel (OEM) vulnerabilities

https://ubuntu.com/security/notices/rss.xml / Mon, 09/07/2026 - 13:30
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 A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges.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.
