In the Linux kernel, the following vulnerability has been resolved: sched_ext: Take cgroup_lock() first in scx_cgroup_lock() scx_cgroup_lock()… (CVE-2026-74593)CVE-2026-74593 0 A deadlock vulnerability in the Linux kernel's sched_ext subsystem was resolved by changing the locking order in the scx_cgroup_lock() function. The issue involved a potential deadlock caused by acquiring cgroup_lock() after write-locking scx_cgroup_ops_rwsem, which could lead to circular wait conditions involving cgroup_mutex and kernfs locks. The fix ensures cgroup_lock() is taken first, preventing the deadlock scenario. Join the discussion | GCVE Database | 08/22/2026, 18:30:25 UTC Added: 08/22/2026, 22:51:31 UTC |
