CVE-2026-43051 is an out-of-bounds read vulnerability in the Linux kernel's Wacom HID driver. The wacom_intuos_bt_irq() function processes Bluetooth HID reports without validating their minimum lengths before copying data into the Wacom structure. Report ID 0x03 requires at least 22 bytes to safely read processed data and battery status; report ID 0x04 falls through to the 0x03 handling logic and requires at least 32 bytes. Maliciously crafted shorter reports can cause reads beyond the received buffer, potentially exposing sensitive kernel memory or causing a kernel crash.

An out-of-bounds read vulnerability in the Linux kernel Wacom HID driver's wacom_intuos_bt_irq function. The advisory identifies affected Rocky Linux 10.2 kernel packages and recommends installing security updates.
An out-of-bounds read vulnerability in the Linux kernel's Wacom Bluetooth HID report handling. Report 0x03 requires at least 22 bytes, and report 0x04 requires 32 bytes; insufficient length validation allows crafted short reports to trigger invalid reads. The reference assigns a CVSS v3 score of 8.1, indicating high confidentiality and availability impact through an adjacent attack vector without authentication or user interaction. The fix adds explicit length checks and warnings for short reports.
