- Summary
- power: supply: max17040: handle missing status supplier
- Details
-
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 POWERSUPPLYPROPSTATUS to a supplier power supply. If no supplier is registered, powersupplygetpropertyfromsupplier() returns -ENODEV and leaves the output value untouched.
max17040getproperty() 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 POWERSUPPLYSTATUS_UNKNOWN when no supplier provides STATUS, and propagate other supplier lookup errors.
