CVE-2026-31638

The CVE-2026-31638 issue affects the Linux kernel rxrpc subsystem. When a client call on a channel has already been torn down, rxrpc_input_packet_on_conn() could still process a to-client packet; rxrpc_try_get_call() could return NULL and there would be no reference to drop. The code path then un...
