Overview

Affected versions of this package are vulnerable to Improper Handling of Unaligned Memory Buffer in the apparmor process due to handling of source blobs from userspace that may be unaligned. An attacker can cause unintended memory access or system instability by supplying specially crafted, unaligned memory data.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
