CVE-2026-45884: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: apparmor: avoid per-cpu hold underflow in aagetbuffer When aagetbuffer pulls from the per-cpu list it unconditionally decrements cache-hold. If hold reaches 0 while count is still non-zero, the unsigned decrement wraps to UINTMAX...
