CVE-2026-31665

A flaw was found in the Linux kernel's netfilter connection tracking nfconntrack component. This vulnerability is a use-after-free error, occurring when a timeout object is deallocated prematurely without waiting for an RCU Read-Copy-Update grace period. This allows concurrent packet processing t...

CVE-2026-31642

The CVE-2026-31642 entry concerns the Linux kernel rxrpc module, where a flaw in call removal was fixed by using list_del_rcu() instead of list_del_init() to prevent infinite loops when reading /proc/net/rxrpc/calls. The underlying issue is that improperly deleting calls could disrupt list handli...
