What the advisory describes

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.

Source: EUVD (ENISA), in the words of the advisory.

Does this concern one of your customers?

Patchlage reports hits and suspected hits. About everything else this system says nothing — neither this page nor the situation report ever claims that an estate is safe.
