Title
power: supply: max17040: handle missing status supplier
Summary
In the Linux kernel, the following vulnerability has been resolved:
power: supply: max17040: handle missing status supplier
MAX17040 does not report charger state itself, so the driver forwards
POWER_SUPPLY_PROP_STATUS to a supplier power supply. If no supplier is
registered, power_supply_get_property_from_supplier() returns -ENODEV and
leaves the output value untouched.
max17040_get_property() currently ignores that error and returns success,
so userspace can read an uninitialized status value from the battery power
supply. This happens on systems that use the fuel gauge without a charger
supplier relationship in firmware.
Return POWER_SUPPLY_STATUS_UNKNOWN when no supplier provides STATUS, and
propagate other supplier lookup errors.
Severity
No CVSS data available.
