CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of the bq25890 power supply driver, where a reference to a secondary charger is not properly released during probe failures or driver detach events, leading to a potential resource leak. This could result in increased memory usage and instability in systems relying on this driver. Linux kernel maintainers and developers working with power management in embedded systems should prioritize addressing this issue to ensure system reliability and resource efficiency.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: power: supply: bq25890: Fix power_supply reference leak bq25890_fw_probe() acquires a reference to a secondary charger using power_supply_get_by_name(), but the reference is not released on later probe failures or on driver detach. In particular, failures after bq25890_fw_probe() returns successfully, such as a failure in bq25890_hw_init(), also leak the reference. Register a device-managed cleanup action immediately after acquiring the secondary charger. This releases the reference on all subsequent probe failures and on driver detach. Found by code review.
