CVE-2024-27001

System crash via incomplete USB endpoint validation

Published May 1, 2024 · Updated May 11, 2026

Improper USB endpoint validation in Linux allows local users to crash the system through a crafted USB device during driver probing. The vmk80xx_find_usb_endpoints() function fails to verify that each discovered endpoint has the transfer type expected for the hardware model, so vmk80xx_reset_device() submits an URB through a mismatched pipe. Triggering requires an unexpected device endpoint layout, and the resulting warning becomes a system crash when panic_on_warn is enabled.
