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.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
