CVE-2024-57986

Kernel crash via missing logical-collection handling

Published Feb 27, 2025 · Updated Aug 5, 2026

Improper input validation in the Linux HID core allows physically proximate attackers to crash the kernel via a malformed HID descriptor. hid_apply_multiplier assumes every Resolution Multiplier belongs to a Logical Collection and mishandles a collection walk that finds none. A crafted report reaches the parser during HID-device enumeration; the bounded consequence is kernel interruption rather than data disclosure.
