CVE-2024-45011: char: xillybus: Check USB endpoints when probing device

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 1371d32b95972d39c1e6e4bae8b6d0df1b573731, 2374bf7558de915edc6ec8cb10ec3291dfab9594, 25ee8b2908200fc862c0434e5ad483817d50ceda; Azure Linux 3.0 ARM 6.6.51.1-1; Azure Linux 3.0 x64 6.6.51.1-1.

Low priority for now. Upgrade to Linux Linux 1371d32b95972d39c1e6e4bae8b6d0df1b573731, 2374bf7558de915edc6ec8cb10ec3291dfab9594, 25ee8b2908200fc862c0434e5ad483817d50ceda; Azure Linux 3.0 ARM 6.6.51.1-1; Azure Linux 3.0 x64 6.6.51.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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 xillyusb_setup_base_eps(). 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 setup_channels(). 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 setup_channels() only checks OUT endpoints.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
