CVE-2026-31639
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix key reference count leak from call->key
When creating a client call in rxrpc_alloc_client_call(), the code obtains a reference to the key. This is never cleaned up and gets leaked when the call is destroyed.
Fix this by freeing call->key in rxrpc_destroy_call().
Before the patch, it shows the key reference counter elevated:
$ cat /proc/keys | grep afs@54321 1bffe9cd I--Q--i 8053480 4169w 3b010000 1000 1000 rxrpc afs@54321: ka $
After the patch, the invalidated key is removed when the code exits:
$ cat /proc/keys | grep afs@54321 $
