A NULL pointer dereference flaw was found in rxrpc_preparse_s in net/rxrpc/server_key.c in the Linux kernel. This flaw allows a local attacker to crash the system or leak internal kernel information.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
