A vulnerability was identified in LM Sensors, which may be exploited by malicious users to conduct symlink attacks and potentially overwrite arbitrary files. The problem is due to an error in the "pwmconfig" script that creates the temporary file "/tmp/fancontrol" insecurely, which may be exploited by local attackers to overwrite or create arbitrary files with the privileges of the user running the vulnerable script.
