  "details": "In the Linux kernel, the following vulnerability has been resolved:  firewire: cdev: fix back-transition for iso_resource_auto client resource  The todo member of iso_resource_auto structure represents the state of the client resource and normally transitions in the following order:      ISO_RES_AUTO_ALLOC -\u003e ISO_RES_AUTO_REALLOC -\u003e ISO_RES_AUTO_DEALLOC  However, concurrent access from the work item and the file descriptor release function can cause the state to transition backwards from ISO_RES_AUTO_DEALLOC to ISO_RES_AUTO_REALLOC.  Prevent the back-transition by checking the current state before updating it in the work item.",
