USN-8488-1: Linux kernel vulnerabilities

It was discovered that some AMD processors did not properly clear data in
the floating point divider unit during speculative execution. A local
attacker could use this to expose sensitive information. (CVE-2025-54505)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
