Description (CNA)
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.
