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 when pm runtime get sync fails, causing the PM reference count to be incremented even though it should not be. This happens in the xiic xfer and xiic i2c remove functions. To fix this issue, pm runtime get sync is replaced 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.
