Descriptions

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.

La función nfqnl_mangle en el archivo net/netfilter/nfnetlink_queue.c en el kernel de Linux versiones hasta 5.18.14, permite a atacantes remotos causar una denegación de servicio (pánico) porque, en el caso de un veredicto nf_queue con un atributo nfta_payload de un byte, un skb_pull puede encontrar un skb-)len negativo

A memory corruption flaw was found in the Linux kernel’s Netfilter subsystem in the way a local user uses the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
