Buffer Validation Flaw in Linux Kernel's HID Component

CVE-2025-38494

What is CVE-2025-38494?

A buffer validation error exists in the Linux kernel's HID component, where the function hid_hw_raw_request() fails to validate the provided buffer and length parameters. This flaw allows low-level transport drivers to circumvent essential checks, leading to the potential use of invalid parameters. This vulnerability highlights the critical need for robust buffer validation to ensure that only safe and accurate data is processed in device communication, significantly impacting overall system integrity.
