Description

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.
