CVE-2025-38142
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (asus-ec-sensors) check sensor index in read_string()
Prevent a potential invalid memory access when the requested sensor is not found.
find_ec_sensor_index() may return a negative value (e.g. -ENOENT), but its result was used without checking, which could lead to undefined behavior when passed to get_sensor_info().
Add a proper check to return -EINVAL if sensor_index is negative.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
[groeck: Return error code returned from find_ec_sensor_index]
