Positive Technologies (AI Summary)

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

Description A runtime power management (PM) reference leak occurs in the tegra i2c driver. When the tegra i2c mutex lock() function fails, the system returns without executing pm runtime put(), which fails to release the reference previously acquired by pm runtime get sync(). This prevents the device from entering runtime suspend, a state where the device is powered down to save energy while the system remains active.

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