UBUNTU-CVE-2024-45011: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Which systems are exposed to this issue?

Systems using the affected Ubuntu Linux kernel packages are exposed when the XillyUSB (xillybus) driver probes a connected XillyUSB device. The listed packages include linux, linux-azure, linux-gcp, linux-gke, linux-riscv, linux-realtime, linux-fips, and linux-azure-fde.

Q: What does an attacker need to exploit the vulnerability?

An attacker would need to present a XillyUSB device whose USB endpoint layout or device-provided endpoint information is invalid. The issue occurs during device probing, when the driver reads and uses endpoint information from the device.

Q: What is the impact of a successful exploit?

The provided severity vector indicates an availability impact, with no indicated impact to confidentiality or integrity. The fix adds validation that required endpoints exist and have the expected bulk endpoint types before the driver accesses them.

Published Sep 11, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: char: xillybus: Check USB endpoints when probing device Ensure, as the driver probes the device, that all endpoints that the driver may attempt to access exist and are of the correct type. All XillyUSB devices must have a Bulk IN and Bulk OUT endpoint at address 1. This is verified in xillyusbsetupbaseeps(). On top of that, a XillyUSB device may have additional Bulk OUT endpoints. The information about these endpoints' addresses is deduced from a data structure (the IDT) that the driver fetches from the device while probing it. These endpoints are checked in setupchannels(). A XillyUSB device never has more than one IN endpoint, as all data towards the host is multiplexed in this single Bulk IN endpoint. This is why setupchannels() only checks OUT endpoints.
