CVE-2026-72182 in Linux
الملخص
بحسب MITRE • 15/08/2026
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.
