"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: mcp251x: fix deadlock in error path of mcp251x_open\n\nThe mcp251x_open() function call free_irq() in its error path with the\nmpc_lock mutex held. But if an interrupt already occurred the\ninterrupt handler will be waiting for the mpc_lock and free_irq() will\ndeadlock waiting for the handler to finish.\n\nThis issue is similar to the one fixed in commit 7dd9c26bd6cf (\"can:\nmcp251x: fix deadlock if an interrupt occurs during mcp251x_open\") but\nfor the error path.\n\nTo solve this issue move the call to free_irq() after the lock is\nreleased. Setting `priv->force_quit = 1` beforehand ensure that the IRQ\nhandler will exit right away once it acquired the lock."
