CVE-2026-72235 batman-adv: retrieve ethhdr after potential skb realloc on RX

In the Linux kernel, the following vulnerability has been resolved: batman-adv: retrieve ethhdr after potential skb realloc on RX pskbmaypull in batadvinterfacerx could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

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...
