CVE-2026-45998

CVE-2026-45998 affects the Linux kernel RxRPC stack. The vulnerability arises when skb_unshare() fails to unshare a packet during rxrpc_input_packet(); the parent’s skb pointer can be NULL, risking a kernel oops in trace_rxrpc_rx_done(). The fix moves the unsharing logic down to rxrpc_input_call_...
