Linux Kernel HID Driver Vulnerability Affecting ALPS Product

CVE-2026-31625

What is CVE-2026-31625?

A vulnerability in the Linux kernel's HID driver for ALPS devices could allow erroneous processing of raw events due to a NULL pointer dereference. This issue arose because the necessary safeguards were not implemented in the ALPS driver, which led to a potential system failure. The problem has been resolved by ensuring that the driver properly checks if the input has been claimed before processing raw events, thereby enhancing the overall stability and security of the driver.
