Описание
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.
Меры по смягчению последствий
This flaw can be mitigated by preventing the affected slip driver from loading during the boot time, and ensuring the module is added to the blacklist file.
