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

Description A reference leak issue has been resolved in the Linux kernel. The problem occurs in the i2c imx xfer() and i2c imx remove() functions, where the pm reference count is not expected to be incremented on return. However, pm runtime get sync will increment the pm reference count even if it fails, resulting in a reference leak. This issue is fixed by replacing pm runtime get sync with pm runtime resume and get to keep the usage counter balanced.

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