CVE-2026-52922
Description
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: dat: handle forward allocation error
batadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb for each DHT candidate, but does not check the return value before passing it to batadv_send_skb_prepare_unicast_4addr(). That function dereferences the skb unconditionally, so a failed allocation triggers a NULL pointer dereference.
Skip forwarding to the current DHT candidate on allocation failure.
