Description OSIDB Bzimport 2024-12-28 10:01:24 UTC 
In the Linux kernel, the following vulnerability has been resolved:

sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset transport

Since transport->sock has been set to NULL during reset transport,
XPRT_SOCK_UPD_TIMEOUT also needs to be cleared. Otherwise, the
xs_tcp_set_socket_timeouts() may be triggered in xs_tcp_send_request()
to dereference the transport->sock that has been set to NULL.
