CVE-2025-39806

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.
