The vulnerability of the selinux_ptracetraceme() function in Linux operating systems allows a hacker to cause a service failure or enhance their privileges.

The vulnerability of the selinuxptracetraceme function in Linux operating systems is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to cause a service failure or increase their privileges...

An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task.
