CVE-2025-39806

CVSS v3.1

7.1

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.15.0-00005-gec5d573d83f4
Description A flaw exists in the Linux kernel related to handling HID (Human Interface Device) multitouch input. A malicious HID device can trigger a slab out-of-bounds access within the mt report fixup() function by providing a report descriptor smaller than 607 bytes. This occurs because the function attempts to access byte offset 607 of the descriptor without verifying its size, leading to a potential memory corruption issue.
Recommendations Update the Linux kernel to version 6.15.0-00005-gec5d573d83f4 or later to address this issue.
