  "description": "In the Linux kernel, the following vulnerability has been resolved:  can: mcp251x: fix resume from sleep before interface was brought up  Since 8ce8c0abcba3 the driver queues work via priv-\u003Erestart_work when resuming after suspend, even when the interface was not previously enabled. This causes a null dereference error as the workqueue is only allocated and initialized in mcp251x_open().  To fix this we move the workqueue init to mcp251x_can_probe() as there is no reason to do it later and repeat it whenever mcp251x_open() is called.  [mkl: fix error handling in mcp251x_stop()]",
