## Overview

In the Linux kernel, the following vulnerability has been resolved:

platform/x86: int1092: Fix potential memory leak in sar_probe()

The memory allocated for device_mode_info in parse_package() called by
sar_get_data() is not freed in some of the error paths in sar_probe().
Fix that by converting to use device managed allocations.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
