GHSA-895C-6CGV-GH76

Vulnerability from github – Published: 2025-07-03 09:30 – Updated: 2025-12-18 21:31

Details

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]

Severity

5.5 (Medium)
