CVE-2025-39818

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.16.0+ #3

Description The Linux kernel contained a flaw in the intel-thc-hid module related to incorrect pointer arithmetic when saving I2C registers. This improper use of a secondary pointer led to a kernel crash and an out-of-bounds write error, specifically a KASAN (Kernel Address Sanitizer) slab-out-of-bounds error during a regmap bulk read operation. The issue stemmed from using an incorrect pointer, causing access to memory outside the allocated region. The vulnerability was addressed by replacing the pointer arithmetic with direct array indexing to ensure safe memory access.

Recommendations Update to Linux kernel version 6.16.0+ #3 or later to resolve this issue.
