AI-suggested
A patch is available and should be applied to affected linux-azure kernel versions. The vendor advisory from Ubuntu confirms that this issue has been fixed. Users should update to the fixed kernel versions to remediate this vulnerability.
Description
A vulnerability in the Linux kernel's iio gyro mpu3050-core driver was fixed by correcting improper error handling of pm_runtime functions. The issue involved not checking the return value of pm_runtime_get_sync(), which could lead to accessing hardware that failed to resume and incorrectly incrementing the device usage count. The fix uses pm_runtime_resume_and_get() to propagate errors and avoid incrementing usage count on failure, and adds pm_runtime_put_autosuspend() on failure in preenable. This vulnerability affects specific linux-azure kernel versions and has a medium severity score.
