CVE-2026-45893 Details
Description
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 vulnerability related to unaligned memory access in the AppArmor component of the Linux kernel has been addressed. This issue arose because the source blob could originate from userspace and may be unaligned, potentially leading to memory access errors. The vulnerability affects the table creation process, where unaligned memory accesses could cause issues. The patch optimizes the copying process by avoiding these unaligned accesses, thereby fixing the potential vulnerability.
Users can apply the latest patches from the Linux kernel stable tree to address this vulnerability. The patched version can be downloaded from the Linux kernel Git repository.
