This leads to a 4-byte out-of-bounds stack\nwrite in the fp[] array, which only has room for 16 elements (0–15).\n\nFix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1."

"value": "AV:L - The vulnerability is reached only through an RTM_NEWQDISC rtnetlink message on an AF_NETLINK socket, i.e. a local syscall interface. Per kernel scoring guidance, tc/netlink qdisc configuration paths are Local.\nAC:L - A single crafted netlink message with TCA_MQPRIO_TC_ENTRY_INDEX=16 deterministically triggers the out-of-bounds write; there is no race, no memory-layout guess, and no timing dependency. The only prerequisite is a multiqueue netdev implementing ndo_setup_tc, which is true of essentially every hardware NIC, DSA user port, and mac80211 wlan interface.\nPR:L - Triggering requires CAP_NET_ADMIN in the target network namespace, which per kernel scoring guidance for tc/qdisc paths is rated Low rather than High. Realistic low-privilege holders include containers granted NET_ADMIN over a namespace holding an SR-IOV VF or passed-through NIC, and non-root TSN/network configuration daemons on automotive and industrial systems.\nUI:N - The attacker performs the entire operation themselves via a netlink socket write; no victim action, mount, or file open is needed.\nS:U - The corruption occurs on the kernel stack of the calling task and stays within the kernel's own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The bug corrupts kernel stack memory beyond the fp[] array, damaging adjacent frame state such as saved registers, the canary, or the in-flight netlink attribute iterator. Such kernel memory corruption is treated as leverageable toward information disclosure, so the higher rating is taken.\nI:H - This is an out-of-bounds write into the kernel stack frame at an attacker-selected trigger point, overwriting data the attacker was never permitted to modify. Out-of-bounds writes are rated High for integrity.\nA:H - On stack-protector kernels (the default for distro, Android, and automotive builds) the write lands on the canary region, so returning from mqprio_parse_tc_entries invokes __stack_chk_fail(), which calls panic() and brings the machine down unrecoverably. Even without the stack protector, the corrupted frame state causes a kernel oops."
