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.
A flaw was found in the Linux kernel's bq25890 power supply driver. The bq25890_fw_probe() function acquires a reference to a secondary charger but fails to release it on subsequent probe failures or driver detach. This reference leak can lead to resource exhaustion over time, potentially allowing a local attacker to cause a Denial of Service (DoS) by making the system unstable or unresponsive.
