Improper resource allocation In kernel

Description

A NULL pointer dereference flaw was found in the Linux kernel's RxRPC/AFS networking stack. When making an AFS call, the call timer can expire before a connection is assigned if the call gets stalled waiting for a connection. This causes a NULL pointer dereference in rxrpc_alloc_txbuf() when attempting to send an ACK.

Mitigation

Update Impact
