Overview

Affected versions of this package are vulnerable to Out-of-Bounds in the aa_dfa_match function. An attacker can cause a kernel memory disclosure and potential denial of service by triggering an out-of-bounds read through a crafted mount operation that results in a missing string terminator, leading to kernel heap contents being leaked and possible kernel crash.

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
