CVE-2024-41046

Kernel memory corruption via descriptor cleanup double-free

Published Jul 29, 2024 · Updated Aug 5, 2026

Double-free in the Lantiq ETOP Ethernet driver in Linux allows attackers to corrupt kernel memory during device detach. ltq_etop_free_channel advances a local loop counter while repeatedly freeing the socket buffer indexed by the unchanged dma.desc field. Reaching the flaw requires RX-channel teardown on a system using the Lantiq ETOP driver, where repeated freeing corrupts kernel memory.
