CVE-2022-36946 (GCVE-0-2022-36946)

Vulnerability from cvelistv5 – Published: 2022-07-27 00:00 – Updated: 2025-05-05 16:13

Summary

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.

Severity

7.5 (High)
