CVE-2026-89555

CVE-2026-89555 is a use-after-free in the Linux kernel's MPLS subsystem. In mpls_select_multipath(), a cached header pointer (hdr) is not reloaded after pskb_may_pull() reallocates the skb head via pskb_expand_head(), leaving hdr pointing to freed memory. A remote attacker can trigger the bug by ...
