CVE-2026-89488

A flaw was found in the Linux kernel's Open vSwitch OVS component. An unprivileged user, operating from a user and network namespace, can trigger a use-after-free vulnerability during network namespace teardown. This occurs because packet processing attempts to use connection tracking CT limit...

CVE-2026-89555

Linux kernel MPLS multipath selection (mpls_select_multipath) contains a slab-use-after-free vulnerability. When mpls_multipath_hash() walks the MPLS label stack, it caches a header pointer (hdr). If pskb_may_pull() subsequently triggers pskb_expand_head() to replace the skb head, the cached poin...
