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...

CVE-2026-31640 rxrpc: Fix use of wrong skb when comparing queued RESP challenge serial

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix use of wrong skb when comparing queued RESP challenge serial In rxrpcpostresponse, the code should be comparing the challenge serial number from the cached response before deciding to switch to a newer response, but...

CVE-2026-31640

CVE-2026-31640 affects the Linux kernel rxrpc component. The issue occurs in rxrpc_post_response() where the code compares the challenge serial number using the newer packet private data instead of the cached/older response, causing the comparison to always be false and potentially preventing the...
