      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ngreybus: raw: fix use-after-free if write is called after disconnect\n\nIf a user writes to the chardev after disconnect has been called, the\nkernel panics with the following trace (with\nCONFIG_INIT_ON_FREE_DEFAULT_ON=y):\n\n        BUG: kernel NULL pointer dereference, address: 0000000000000218\n         ...\n        Call Trace:\n         <TASK>\n         gb_operation_create_common+0x61/0x180\n         gb_operation_create_flags+0x28/0xa0\n         gb_operation_sync_timeout+0x6f/0x100\n         raw_write+0x7b/0xc7 [gb_raw]\n         vfs_write+0xcf/0x420\n         ? task_mm_cid_work+0x136/0x220\n         ksys_write+0x63/0xe0\n         do_syscall_64+0xa4/0x290\n         entry_SYSCALL_64_after_hwframe+0x77/0x7f\n\nDisconnect calls gb_connection_destroy, which ends up freeing the\nconnection object. When gb_operation_sync is called in the write file\noperations, its gets a freed connection as parameter and the kernel\npanics.\n\nThe gb_connection_destroy cannot be moved out of the disconnect\nfunction, as the Greybus subsystem expect all connections belonging to a\nbundle to be destroyed when disconnect returns.\n\nTo prevent this bug, use a rw lock to synchronize access between write\nand disconnect. This guarantees that the write function doesn't try\nto use a disconnected connection.",
