CVE-2024-58020

Kernel crash via unchecked allocation failure

Published Feb 27, 2025 · Updated Sep 8, 2026

NULL pointer dereference in Linux HID multitouch allows local users to crash the kernel during multitouch device configuration. mt_input_configured stores the result of devm_kasprintf without checking for allocation failure, so a NULL device name is later dereferenced. Exploitation requires local low-privileged access and a failing allocation while a multitouch input device is configured; no data read or write is reported.
