{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: dat: handle forward allocation error\n\nbatadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb\nfor each DHT candidate, but does not check the return value before passing\nit to batadv_send_skb_prepare_unicast_4addr(). That function dereferences\nthe skb unconditionally, so a failed allocation triggers a NULL pointer\ndereference.\n\nSkip forwarding to the current DHT candidate on allocation failure.",
