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.","state":0,"publishedAt":"2024-06-18T19:15:07.892+00:00","modifiedAt":"2026-10-15T00:43:06.154+00:00","affected":[{"ecosystem":"Vendor
