CVE-2026-74593

This CVE affects the Linux kernel 's sched_ext subsystem. The root cause is a lock ordering bug in scx_cgroup_lock(), which acquires scx_cgroup_ops_rwsem (write) before cgroup_lock(). This ordering can create a deadlock through kernfs when concurrent operations on cgroup rmdir and cpu.weight writ...
