Severity

8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: HID: wacom: fix crash in wacom_aes_battery_handler() Commit fd2a9b29dc9c ("HID: wacom: Remove AES power_supply after extended inactivity") introduced wacom_aes_battery_handler() which is scheduled as a delayed work (aes_battery_work). In wacom_remove(), aes_battery_work is not canceled. Consequently, if the device is removed while aes_battery_work is still pending, then hard crashes or "Oops: general protection fault..." are experienced when wacom_aes_battery_handler() is finally called. E.g., this happens with built-in USB devices after resume from hibernate when aes_battery_work was still pending at the time of hibernation. So, take care to cancel aes_battery_work in wacom_remove().

This matches the adjacent-network scoring used for other Wacom HID report-processing flaws.\nAC:L - The attacker device controls every step \u2014 the report descriptor that sets WACOM_QUIRK_AESPEN, the pen report with sense=0 that arms the work, and the disconnect that frees `struct wacom` \u2014 and the 30-minute delay window guarantees the work is still pending at removal. No race must be won and no uncontrollable state is required.\nPR:N - Everything happens inside kernel HID transport and driver probe/report/remove handling; no user account, credential, or capability on the target is involved. The attacker only needs their device connected to the host.\nUI:N - Once the device is connected, arming the delayed work and then tearing down the link are entirely device-driven with no action by any user on the target. Consistent with prior Wacom HID CVEs scored UI:N.\nS:U - The use-after-free corrupts kernel heap memory and executes within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed devm-allocated `struct wacom` is a sprayable slab object whose contents are subsequently used as a workqueue pointer, work function pointer, and `hdev` pointer, giving an attacker who grooms the slab an arbitrary-read/kernel-memory-disclosure primitive.\nI:H - `process_one_work()` invokes `work-\u003efunc()` read from the freed object and `devres_release_group()` walks stale list data invoking release callbacks, yielding control-flow hijack and arbitrary-write potential; the leftover armed timer in the timer wheel adds list-corruption write primitives.\nA:H - The commit explicitly reports \"hard crashes or \u0027Oops: general protection fault\u0027\" when the pending work fires after device removal, and the attacker can trigger this repeatedly by reconnecting and disconnecting."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
