AI-suggested
A patch is available and should be applied to affected linux-aws kernel versions to fix the device reference leak. The fix replaces improper kfree() calls with put_device() in the error path. Users should update to patched kernel versions as provided by their vendor.
Description
A vulnerability in the Linux kernel's gpu host1x driver was fixed to address a device reference leak in the host1x_device_parse_dt() error path. The issue involved improper release of an embedded device structure, leading to a reference leak when an error occurred. This flaw was identified through static analysis and manual review. The vulnerability affects specific linux-aws kernel versions. A patch is available to correct this issue.
