Overview

CVE-2026-43051 is a high-severity vulnerability. It was published on May 1, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq

The wacom_intuos_bt_irq() function processes Bluetooth HID reports

without sufficient bounds checking. A maliciously crafted short report

can trigger an out-of-bounds read when copying data into the wacom

structure.

Specifically, report 0x03 requires at least 22 bytes to safely read

the processed data and battery status, while report 0x04 (which

falls through to 0x03) requires 32 bytes.

Add explicit length checks for these report IDs and log a warning if

a short report is received.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
