CVE-2024-53213

Kernel memory corruption via lan78xx buffer double free

Published Dec 27, 2024 · Updated Jun 1, 2026

Double free in the Linux kernel lan78xx USB network driver allows local users to corrupt kernel memory during device probing. In lan78xx_probe(), usb_free_urb() frees the interrupt buffer through URB_FREE_BUFFER before the same buffer is passed to kfree(). Exploitation requires physical access to relevant USB hardware or CAP_SYS_ADMIN privileges, and public sources establish no more specific outcome.
