CVE-2026-72234

The CVE relates to the Linux kernel’s batman-adv code. A use-after-free could occur when pskb_may_pull() reallocates the buffer behind skb, and pointers (notably the unicast_packet pointer) are not reassigned, after skb data is accessed. The issue was fixed by ensuring reassignment for affected p...
