CVE-2024-26651

System crash via ignored endpoint-discovery failure

Published Mar 27, 2024 · Updated May 12, 2026

Improper input validation in affected Linux 3.14 and later sr9800 drivers allows local users to crash the system during USB binding. The sr9800_bind function ignores a failure from usbnet_get_endpoints and continues initialization without valid endpoint state. Triggering the flaw requires local low-privileged access and an SR9800 USB network device whose endpoint discovery fails; the documented consequence is a system crash.
