local syscalls on an AF_BLUETOOTH HCI control socket \\u2014 sendmsg() of MGMT_OP_REMOVE_ADV_MONITOR and ioctl(HCIDEVDOWN); the MGMT interface is a host-local control channel with no over-the-air component, so a remote or adjacent Bluetooth peer cannot reach it.\\nAC:L - The attacker drives both sides of the race from its own threads (queue the adv-monitor removal, then power the controller down) and can retry in a tight loop; syzbot produced a working reproducer, and no condition depends on external state.\\nPR:L - Reaching remove_adv_monitor requires a trusted mgmt socket, i.e. an unprivileged-user-accessible Bluetooth control path that on real systems (Android bluetooth UID, desktop bluetoothd, embedded BT services) is exposed to low-privilege local actors; matches the PR:L scoring of the sibling fixes CVE-2025-38118 and CVE-2025-39981 for this same code.\\nUI:N - The attacker performs every step itself via write() and ioctl() on sockets it owns; no victim action, mount, or configuration change is needed.\\nS:U - The freed object, the corruption, and the resulting privilege gain are all inside the kernel\u0027s own security authority \\u2014 no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - Use-after-free on a kmalloc\u0027d mgmt_pending_cmd lets the attacker spray the reclaimed slot and control cmd-\u003eparam and cmd-\u003esk, turning the dereference in mgmt_remove_adv_monitor_sync/_complete into an arbitrary kernel read whose result is returned to userspace in the mgmt_cmd_complete reply.\\nI:H - The destroy callback performs list_del() on the freed object plus sock_put() and kfree() on attacker-influenceable pointers, yielding a controlled write and a fake-sock function-pointer path suitable for control-flow hijacking and privilege escalation.\\nA:H - Even without successful heap grooming, the stale dereference and list unlink in the hci0 workqueue corrupts kernel memory and reliably oopses or panics the machine, killing the

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",

TBF is out of tokens so\n it schedules itself for later.\n\n* the second packet is sent and TBF tries to queues it to SFQ. qdisc\n qlen is now 2 and because the SFQ limit is 1 the packet is dropped\n by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,\n however q-\u003etail is not NULL.\n\nAt this point, assuming no more packets are queued, when sch_dequeue\nruns again it will decrement the qlen for the current empty slot\ncausing an underflow and the subsequent out of bounds access.",
