EUVD-2026-59134

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...

In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: reacquire gw address after skb realloc The pskbmaypull called by batadvblaisbackbonegw could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

CVE-2026-72233

In the Linux kernel, the batman-adv component (bla) vulnerability is resolved: pskb_may_pull() used by batadv_bla_is_backbone_gw() could reallocate the buffer behind the skb, making variables pointing to the old buffer prone to use-after-free. The issue is mitigated by the patch that ensures poin...

EUVD-2026-59131

In the Linux kernel, the following vulnerability has been resolved: batman-adv: ensure minimal ethernet header on TX As documented in commit 8bd67ebb50c0 "net: bridge: xmit: make sure we have at least eth header len bytes", it is possible by for a local user with eBPF TC hook access to attach a t...

CVE-2026-72231

CVE-2026-72231 affects the Linux kernel’s batman-adv TT (traffic test) logic. The vulnerability arises in batadv_send_tt_request(), which previously allocated a tt_req_node for a destination originator, potentially allowing multiple TT requests to be sent concurrently. The issue is that a send-bu...

CVE-2026-72232

CVE-2026-72232 relates to the Linux kernel/batman-adv stack, where a local user with eBPF TC hook access could trigger a packet truncation that redirects to a batman-adv interface. The vulnerability arises because the code assumes at least ETH_HLEN bytes are available and may read beyond the buff...

CVE-2026-72231 batman-adv: tt: avoid request storms during pending request

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: avoid request storms during pending request batadvsendttrequest allocates a ttreqnode when none exists for the destination originator node. This should prevent that a multiple TT requests are send at the same time...
