Summary
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.
