A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an 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.
