CVE-2016-3136

Published: 02 May 2016

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.

From the Ubuntu security team

Sergej Schumilo, Hendrik Schwartke, and Ralf Spenneberg discovered that the MCT USB RS232 Converter device driver in the Linux kernel did not properly validate USB device descriptors. An attacker with physical access could use this to cause a denial of service (system crash).

Priority

Low
