CVE-2010-4170
The staprun runtime tool in SystemTap 1.3 does not properly clear the environment before executing modprobe, which allows local users to gain privileges by setting the MODPROBE_OPTIONS environment variable to specify a malicious configuration file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
