  "description": "In the Linux kernel, the following vulnerability has been resolved:  greybus: raw: fix use-after-free if write is called after disconnect  If a user writes to the chardev after disconnect has been called, the kernel panics with the following trace (with CONFIG_INIT_ON_FREE_DEFAULT_ON=y):          BUG: kernel NULL pointer dereference, address: 0000000000000218          ...

When gb_operation_sync is called in the write file operations, its gets a freed connection as parameter and the kernel panics.  The gb_connection_destroy cannot be moved out of the disconnect function, as the Greybus subsystem expect all connections belonging to a bundle to be destroyed when disconnect returns.  To prevent this bug, use a rw lock to synchronize access between write and disconnect. This guarantees that the write function doesn\u0027t try to use a disconnected connection.",
