CVE-2023-54110

Information disclosure via rndis_query integer overflow

Published Dec 24, 2025 · Updated Dec 24, 2025

Integer overflow in the rndis_host USB driver in Linux allows attackers to disclose kernel memory via a crafted RNDIS response. The rndis_query function adds attacker-controlled 32-bit offset and length values to eight using wrap-prone arithmetic, letting an oversized offset pass validation and produce a pointer beyond the response buffer. Exploitation requires control of an RNDIS response delivered to the driver; the reported consequence is out-of-bounds information disclosure.
