Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.3.9
Description
The issue is related to a use-after-free error in the
aa audit rule init() function, located in security/apparmor/audit.c, which can be exploited by a remote attacker to execute arbitrary code. The error occurs when aa label parse() fails in aa audit rule init().Recommendations
For Linux kernel versions prior to 5.3.9, update to version 5.3.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the
aa audit rule init() function until a patch is available.Correção
