CVE-2024-26642 is a vulnerability in the Linux kernel Netfilter nf_tables subsystem. nf_tables accepted anonymous sets configured with the timeout flag, a combination not intended for userspace use. The fix rejects creation of anonymous timeout sets from userspace while retaining an exception for NFT_SET_EVAL to preserve compatibility with legacy meter functionality.
