CVE-2026-46232

Kernel-memory disclosure via unchecked touch-report count

Published May 28, 2026 · Updated May 28, 2026

Out-of-bounds read in Linux Kernel branches starting at 6.2 allows adjacent attackers to disclose kernel memory through crafted HID reports. dualshock4_parse_report trusts the device-supplied num_touch_reports value and iterates beyond the touch_reports array, emitting derived data through evdev. A bonded or emulated DualShock 4 within Bluetooth range, or a USB-connected device, can leak up to about 2 KiB and trigger a kernel panic.
