CWE-20Published: March 12, 2017· Updated: Jun 17, 2026
5.5
CVSS v3.1
Official Description
The add_probe function in modutils/modprobe.c in BusyBox before 1.23.0 allows local users to bypass intended restrictions on loading kernel modules via a / (slash) character in a module name, as demonstrated by an "ifconfig /usbserial up" command or a "mount -t /snd_pcm none /" command.
Technical Analysis
CVE-2014-9645 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 5.5.
