net: usb: pegasus: don't rely on id table pointer arithmetic

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 05d47f540d85c8f6697ec5cfc1aa7b4f96a5b31b, 61b84e964a829d534f24eab4cbd4035d22b52601, 7654812b65047349ea4c111eed42c4315a00e462; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 05d47f540d85c8f6697ec5cfc1aa7b4f96a5b31b, 61b84e964a829d534f24eab4cbd4035d22b52601, 7654812b65047349ea4c111eed42c4315a00e462; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net: usb: pegasus: don't rely on id table pointer arithmetic The current code is broken when dynamic ID is involved; in such cases usb_device_id parameter of probe lives on the heap and the pointer arithmetic will get an index that is wildly out of bound. Instead of keeping a side table for additional information, use driver_info field of the usb_device_id. The dynamic ID parsing code needs to be updated for this; convert it to just write to the reserved entry for dynamic ID and remove the weird loop.
