USB Endpoint Validation Flaw in Linux Pegasus Driver Causes Crash

Publication date: 2026-03-25

Last updated on: 2026-05-29

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: net: usb: pegasus: validate USB endpoints The pegasus driver should validate that the device it is probing has the proper number and types of USB endpoints it is expecting before it binds to it. If a malicious device were to not have the same urbs the driver will crash later on when it blindly accesses these endpoints.

Executive Summary

This vulnerability exists in the Linux kernel's pegasus USB driver. The driver fails to properly validate that a USB device it is probing has the expected number and types of USB endpoints before binding to it. If a malicious USB device does not have the expected endpoints, the driver may later crash when it tries to access these missing endpoints blindly.

Impact Analysis

The impact of this vulnerability is that a malicious USB device could cause the Linux kernel to crash by exploiting the pegasus driver's lack of endpoint validation. This could lead to system instability or denial of service.
