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...

CVE-2026-31638 rxrpc: Only put the call ref if one was acquired

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Only put the call ref if one was acquired rxrpcinputpacketonconn can process a to-client packet after the current client call on the channel has already been torn down. In that case chan-call is NULL, rxrpctrygetcall retur...
