CVE-2026-80783Hinoki check available

System crash via nested HID double reports

Published Sep 4, 2026 · Updated Sep 4, 2026

Stack overflow in the Linux Magic Mouse HID driver allows physically proximate attackers to crash the system via crafted HID reports. magicmouse_raw_event() recursively splits nested DOUBLE_REPORT_ID wrappers without limiting re-entry or recursion depth. Exploitation requires a malicious HID device matched to the driver; stack exhaustion causes a panic with CONFIG_VMAP_STACK or memory corruption without it.
