  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirewire: cdev: fix back-transition for iso_resource_auto client resource\n\nThe todo member of iso_resource_auto structure represents the state of the\nclient resource and normally transitions in the following order:\n\n    ISO_RES_AUTO_ALLOC -\u003e ISO_RES_AUTO_REALLOC -\u003e ISO_RES_AUTO_DEALLOC\n\nHowever, concurrent access from the work item and the file descriptor\nrelease function can cause the state to transition backwards from\nISO_RES_AUTO_DEALLOC to ISO_RES_AUTO_REALLOC.\n\nPrevent the back-transition by checking the current state before\nupdating it in the work item.",
