  "description": "In the Linux kernel, the following vulnerability has been resolved:  btrfs: fix match incorrectly in dev_args_match_device  syzkaller found a failed assertion:    assertion failed: (args-\u003Edevid != (u64)-1) || args-\u003Emissing, in fs/btrfs/volumes.c:6921  This can be triggered when we set devid to (u64)-1 by ioctl. In this case, the match of devid will be skipped and the match of device may succeed incorrectly.  Patch 562d7b1512f7 introduced this function which is used to match device. This function contains two matching scenarios, we can distinguish them by checking the value of args-\u003Emissing rather than check whether args-\u003Edevid and args-\u003Euuid is default value.",
