CVE-2026-31625 Details
Description
In the Linux kernel, the following vulnerability has been resolved: HID: alps: fix NULL pointer dereference in alps_raw_event() Commit ecfa6f34492c ("HID: Add HID_CLAIMED_INPUT guards in raw_event callbacks missing them") attempted to fix up the HID drivers that had missed the previous fix that was done in 2ff5baa9b527 ("HID: appleir: Fix potential NULL dereference at raw event handle"), but the alps driver was missed. Fix this up by properly checking in the hid-alps driver that it had been claimed correctly before attempting to process the raw event.
A NULL pointer dereference vulnerability has been identified in the Linux kernel HID Alps driver, specifically in the raw event handling function. This issue arises because the driver did not properly check if it had been claimed before processing raw events, leading to a potential crash. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched kernel can be found on the official Linux kernel website.
