CVSS 3.1
7.1 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:NCVE-2026-64111
High (7.1) in linux linux kernel. EPSS 0.1% chance of exploitation in the next 30 days.
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.
