Описание

In the Linux kernel, the following vulnerability has been resolved: apparmor: Fix & Optimize table creation from possibly unaligned memory Source blob may come from userspace and might be unaligned. Try to optize the copying process by avoiding unaligned memory accesses.

  • Added Fixes tag
  • Added "Fix &" to description as this doesn't just optimize but fixes a potential unaligned memory access [jj: remove duplicate word "convert" in comment trigger checkpatch warning]

    A flaw was found in the Linux kernel's AppArmor security module. This vulnerability occurs when AppArmor attempts to create tables from user-provided data that may be unaligned in memory. A local attacker could exploit this by providing specially crafted input, leading to unaligned memory accesses. This could result in system instability or unexpected behavior.
