UBUNTU-CVE-2025-38142: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: What access does an attacker need to trigger this issue?

The issue has local attack vector, low attack complexity, and requires low privileges. No user interaction is required.

Q: Which Ubuntu kernel packages are listed as affected?

The listed packages are ubuntu/linux-azure-fde, ubuntu/linux-riscv, ubuntu/linux-realtime, ubuntu/linux-hwe-edge, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-gke, and ubuntu/linux-gkeop.

Q: What is the impact if the flaw is triggered?

The reported impact is availability loss. A missing sensor can produce a negative sensor index that is passed to get_sensor_info(), potentially causing invalid memory access and undefined behavior.

Q: How does the fix prevent the problem?

The fix checks whether find_ec_sensor_index() returned a negative value before calling get_sensor_info(). It returns -EINVAL when the requested sensor is not found.

Published Jul 3, 2025

Updated

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