CVE-2026-80838 vxlan: keep the last remote linked during FDB flush

In the Linux kernel, the following vulnerability has been resolved: vxlan: keep the last remote linked during FDB flush A non-nexthop FDB entry is expected to have at least one remote while it remains reachable through the FDB hash table. A filtered bulk flush violates this invariant when every...

CVE-2026-80838

CVE-2026-80838 affects the vxlan subsystem in the Linux kernel. The root cause is a race condition during a filtered bulk FDB flush: vxlan_fdb_dst_destroy() unlinks the last remote from a non-nexthop FDB entry before the parent entry is removed from the hash table. During this window, an RCU read...

CVE-2026-80758

CVE-2026-80758 is a use-after-free vulnerability in the Linux kernel's futex subsystem. The flaw is in futex_private_hash_put(), which drops its reference to the private hash (fph) before evaluating fph->mm for wake_up_var(). Because futex_ref_put() re-enables preemption before returning, a ta...

CVE-2026-80758 futex: Avoid private hash use-after-free on final put

In the Linux kernel, the following vulnerability has been resolved: futex: Avoid private hash use-after-free on final put futexprivatehashput drops the reference to fph before evaluating fph-mm for wakeupvar. futexrefput enables preemption again before returning. If that put drops the final...

kernel: locking/rt: Fix the incorrect RCU protection in rt_spin_unlock()

A flaw was found in the Linux kernel. The rtspinunlock function, and similar real-time RT locking mechanisms, incorrectly release Read-Copy-Update RCU protection before fully unlocking, leading to a Use-After-Free UAF vulnerability. This issue could allow a local attacker to potentially cause a...

kernel: net/sched: act_api: use RCU with deferred freeing for action lifecycle

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free UAF vulnerability,...
