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

A deadlock vulnerability exists in the Linux kernel's netfilter nf_conntrack component. When TCP or SCTP conntrack paths emit invalid-packet logs while ct->lock is held, and logging is routed to nfnetlink_log with conntrack export enabled, the log path can re-enter conntrack netlink glue that ...

CVE-2026-74593 sched_ext: Take cgroup_lock() first in scx_cgroup_lock()

In the Linux kernel, the following vulnerability has been resolved: schedext: Take cgrouplock first in scxcgrouplock scxcgrouplock write-locks scxcgroupopsrwsem and then takes cgrouplock, which can deadlock through kernfs: scx enable/disable cgroup rmdir cpu.weight write ------------------...

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...
