AI Analysis

Impact

A missing bounds check in the wacom_hid_set_device_mode function of the Wacom HID driver allows an out‑of‑bounds write that can overwrite privileged memory, elevating an attacker’s privileges without needing additional execution rights or user interaction.

Affected Systems

Android devices that include the Wacom HID driver are affected. The vendor identification is restricted to Google:Android, and no specific device models are enumerated in the advisory.

Risk and Exploitability

The CVSS score of 6.8 indicates medium severity. The absence of an EPSS score and the fact that the vulnerability is not listed in CISA KEV do not diminish its risk: exploiting the flaw requires only physical access to the device and the ability to transmit crafted HID input via a USB port. No remote or user‑initiated action is necessary, making the attack path straightforward for a physically present attacker.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the Android security patch that fixes the missing bounds check in the wacom_hid_set_device_mode function.
  • Disable USB HID functionality on the device where it is not needed, such as by adjusting the USB configuration or using a device‑policy manager to block HID traffic.
  • Enforce strong physical security measures: lock the device when unattended, use secure lock‑screen credentials, and restrict unauthorized USB access through enterprise device‑management policies.
