CVE-2016-3136: The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 allows physically proximate attackers…
Noroxi assessment
Priority: Monitor (action score 19/100)
- 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: 1.7% (FIRST EPSS); higher than 78.8% 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) 4.5.1-1; linux (Debian:7) 3.2.81-1; linux (Debian:8) 3.16.7-ckt25-2+deb8u2.
Low priority for now. Upgrade to linux (Debian:12) 4.5.1-1; linux (Debian:7) 3.2.81-1; linux (Debian:8) 3.16.7-ckt25-2+deb8u2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors.
