CVE-2022-1215

Code execution via device-name format string

Published May 31, 2022 · Updated Aug 2, 2024

Format string injection in affected freedesktop.org libinput releases beginning with 1.10 allows attackers to execute code via a crafted device name. In src/evdev.c, a device name becomes part of a log format string that caller-installed handlers commonly pass to printf without neutralizing directives. Exploitation requires control of a kernel input-device name through a facility such as /dev/uinput or Bluetooth, and code runs with the caller's privileges, which can be root under X.Org.
