Title
HID: intel-ish-hid: ipc: Fix potential use-after-free in work function
Summary
In the Linux kernel, the following vulnerability has been resolved: HID: intel-ish-hid: ipc: Fix potential use-after-free in work function When a reset notify IPC message is received, the ISR schedules a work function and passes the ISHTP device to it via a global pointer ishtp_dev. If ish_probe() fails, the devm-managed device resources including ishtp_dev are freed, but the work is not cancelled, causing a use-after-free when the work function tries to access ishtp_dev. Use devm_work_autocancel() instead, so that the work is automatically cancelled if probe fails.
Severity

Reachability requires local access on a system with ISH, matching other intel-ish-hid scores (AV:L, not AV:P).\nAC:L - This is a use-after-free from scheduling fw_reset_work without cancelling it on probe failure/teardown; UAF bugs are AC:L unless the attacker cannot influence the race. Driver bind/teardown and FW reset notify give a practical way to drive both sides of the lifecycle race.\nPR:L - No capability-gated syscall is required to be on the system when ISH probe fails or FW reset work runs against freed state; related ISH reset and probe-error work bugs are scored PR:L. Deliberate sysfs unbind would be PR:H, so PR:L is chosen as the higher-severity defensible option.\nUI:N - Exploitation does not require a victim to perform an action such as opening a file or clicking; the work is scheduled from the ISH ISR/firmware reset path during driver probe/teardown.\nS:U - Impact is confined to the host kernel\u0027s security authority (memory corruption/privilege escalation in kernel context), with no VM, IOMMU, or other security-boundary crossing.\nC:H - Use-after-free of ishtp_device via the global ishtp_dev pointer in fw_reset_work_fn enables reclaim and controlled reuse of the object, which can be leveraged for arbitrary kernel memory disclosure.\nI:H - The same UAF on a rich ishtp_device object (lists, callbacks, HW ops) enables heap reuse for arbitrary write and control-flow hijacking in kernel context.\nA:H - Dereferencing freed ishtp_dev in the reset work path causes kernel oops/panic even without full exploitation, so availability impact is High."
