CVE 描述
In the Linux kernel, the following vulnerability has been resolved:
power: supply: max17040: propagate register read errors
max17040_get_vcell() and max17040_get_soc() ignore errors returned by
regmap_read(). When an I2C transfer fails, the uninitialized register
value is converted and reported to userspace as a valid voltage or state
of charge. The polling worker can also replace the cached state of charge
with the bogus value and emit a spurious change event.
Propagate read errors through the power supply get_property callback and
keep the last valid cached state of charge when polling fails.
