  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: taprio: always validate TCA_TAPRIO_ATTR_PRIOMAP\n\nIf one TCA_TAPRIO_ATTR_PRIOMAP attribute has been provided,\ntaprio_parse_mqprio_opt() must validate it, or userspace\ncan inject arbitrary data to the kernel, the second time\ntaprio_change() is called.\n\nFirst call (with valid attributes) sets dev->num_tc\nto a non zero value.\n\nSecond call (with arbitrary mqprio attributes)\nreturns early from taprio_parse_mqprio_opt()\nand bad things can happen.",
