USN-8566-1: Linux kernel vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

CVE-2026-64178

A flaw was found in the Linux kernel's Bluetooth Network Encapsulation Protocol BNEP module. A local attacker with administrative network capabilities CAPNETADMIN could exploit a use-after-free vulnerability in the bnepaddconnection function. This occurs because the function fails to properly...
