CVE-2026-74593

A flaw was found in the Linux kernel's schedext component. An incorrect locking order within the scxcgrouplock function can lead to a deadlock. This occurs when certain cgroup operations, such as enabling/disabling scx or removing a cgroup, happen concurrently with cpu.weight writes. A local...

CVE-2026-74624

A flaw was found in the Linux kernel's netfilter component. Specifically, the TCP and SCTP connection tracking conntrack paths can attempt to log invalid packets while a critical lock is still held. If invalid logging is routed to nfnetlinklog and conntrack export is enabled, this can lead to a...

CVE-2026-74686

This vulnerability affects the Linux kernel 's rqspinlock (queued read-copy spinlock) implementation. When an ABBA deadlock is detected, the waiter queue's tail is not reset, causing the detecting CPU to wait indefinitely for a next waiter that may never arrive. This leads to intermittent stalls ...

EUVD-2026-64595

In the Linux kernel, the following vulnerability has been resolved: futex: Prevent robust futex exit race some more A robust futex unlock stores 0 over the whole futex value - wiping FUTEXWAITERS - and wakes a single waiter. That wakeup is a one-shot notification: the protocol relies on its...

CVE-2026-74624

CVE-2026-74624 is a deadlock vulnerability in the Linux kernel 's netfilter/nf_conntrack subsystem. The TCP and SCTP conntrack paths can emit invalid-packet logs while the ct->lock spinlock is still held. When invalid logging is routed to nfnetlink_log and conntrack export is enabled, the log ...

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...
