CVE-2024-26673
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_ct: sanitize layer 3 and 4 protocol number in custom expectations - Disallow families other than NFPROTO_{IPV4,IPV6,INET}. - Disallow layer 4 protocol with no ports,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
