Summary

In the Linux kernel's power supply subsystem (charger-manager), is_full_charged() calls power_supply_get_by_name() and if the voltage condition is met, returns true without releasing the reference, causing a refcount leak. The fix sets a flag and jumps to the out label where the reference is properly released.

Risk Assessment

Reference leak can lead to improper resource management and potentially cause failures or unpredictable behavior in battery management.

Recommendation

Install the kernel patch to avoid reference leaks in the charger manager.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: power: supply: charger-manager: fix refcount leak in is_full_charged() In is_full_charged(), power_supply_get_by_name() is called to obtain a reference to the fuel_gauge power supply. If the voltage check (uV >= desc->fullbatt_uV) succeeds, the function returns true directly without releasing the reference, leaking the refcount. Fix this by setting a flag and jumping to the out label where power_supply_put() properly drops the reference.
