CVE-2026-43051

Severity CVSS v4.0:
Pending analysis
Type:
CWE-125 Out-of-bounds Read
Publication date:
01/05/2026
Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq<br /> <br /> The wacom_intuos_bt_irq() function processes Bluetooth HID reports<br /> without sufficient bounds checking. A maliciously crafted short report<br /> can trigger an out-of-bounds read when copying data into the wacom<br /> structure.<br /> <br /> Specifically, report 0x03 requires at least 22 bytes to safely read<br /> the processed data and battery status, while report 0x04 (which<br /> falls through to 0x03) requires 32 bytes.<br /> <br /> Add explicit length checks for these report IDs and log a warning if<br /> a short report is received.
