CVE-2026-74746

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

CVE-2026-80521

A flaw was found in the Linux kernel's afunix component. A race condition during concurrent send and close operations can lead to the garbage collector GC partially freeing a Strongly Connected Component SCC. This inconsistent state may cause subsequent GC operations to iterate over a partially...
