CVE-2026-52916

CVE-2026-52916 affects the Linux kernel’s BATMAN-adv frag handling. A crafted BATADV_UNICAST_FRAG packet can defragment into another BATADV_UNICAST_FRAG, causing unbounded recursion in batadv_batman_skb_recv() and leading to kernel stack exhaustion. The published description specifies that refrag...

CVE-2026-52914

In the Linux kernel, the batman-adv component is affected by CVE-2026-52914. The root cause is an accounting bug where the accumulated fragment length used for validating queued fragment chains can be truncated during updates. This allows malformed fragment chains to bypass validation and drive r...
