Noroxi assessment

Priority: Monitor (action score 18/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.5% (FIRST EPSS); higher than 75.7% of all records.
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: linux (Debian:12) 4.4.2-1; kernel-default (SUSE:Linux Enterprise Desktop 12) 3.12.60-52.49.1; kernel-source (SUSE:Linux Enterprise Desktop 12) 3.12.60-52.49.1.

Low priority for now. Upgrade to linux (Debian:12) 4.4.2-1; kernel-default (SUSE:Linux Enterprise Desktop 12) 3.12.60-52.49.1; kernel-source (SUSE:Linux Enterprise Desktop 12) 3.12.60-52.49.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.
