CVE-2024-45008

Service interruption via unbounded multitouch slot allocation

Published Sep 4, 2024 · Updated May 11, 2026

Allocation-size flaw in the Linux kernel allows local users to trigger excessive memory allocation through a crafted UI_DEV_CREATE ioctl. The input_mt_init_slots() path accepts the userspace-controlled num_slots value and uses it for bitmap allocation without enforcing an upper bound. Access to the uinput device and permission to issue the ioctl are required; the resulting resource exhaustion can interrupt service without reported data exposure or code execution.
