Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the pinconf generic parse dt config() function within the pin control subsystem. If the parse dt cfg() function fails, the cleanup logic is bypassed, resulting in a memory leak of the cfg buffer. The issue is resolved by ensuring kfree(cfg) is called before returning from the function when parse dt cfg() fails.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
