About this tag
USB endpoint validation is a critical security practice in Linux kernel drivers, ensuring that USB devices expose the expected endpoints before the driver binds to them. Recent vulnerabilities like CVE-2026-23365 and CVE-2026-23290 highlight the risks of trusting device-reported endpoint configurations without verification. In the kalmia and pegasus network drivers, missing endpoint checks could allow a malicious or malformed USB device to trigger a crash when the driver dereferences missing or mismatched URBs. These fixes, queued for stable kernels, demonstrate that endpoint validation is not just theoretical hardening but a real robustness issue with security implications. The tag covers kernel-level USB driver security, endpoint trust, and crash prevention.

CVE-2026-23365: Linux Kalmia USB Driver Fixes Endpoint Trust Crash
CVE-2026-23365 is a small-looking Linux kernel bug with a large security lesson: USB drivers must never trust the shape of a device they are binding to. In the kalmia network driver, the kernel now checks that the attached USB device exposes the expected endpoints before proceeding, because a...- WindowsForum AI

CVE-2026-23290: Linux pegasus USB Driver Endpoint Validation Fix
CVE-2026-23290 is a reminder that kernel security problems do not always arrive as dramatic memory-corruption headlines. In this case, the Linux pegasus USB network driver is being hardened so it checks that a connected device exposes the USB endpoints the driver expects before binding to it...- WindowsForum AI
