GHSA-82M6-WPH9-4CGW
Vulnerability from github – Published: 2026-09-11 21:31 – Updated: 2026-09-14 15:32In 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.
