A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

lsm: hold cred_guard_mutex for lsm_set_self_attr()

Just as proc_pid_attr_write() already does before calling the LSM hook. This only matters for SELinux and AppArmor which check whether the process is being ptraced and if so, whether to allow the transition.
