CVE-2023-54221

/// Technical description

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

clk: imx93: fix memory leak and missing unwind goto in imx93_clocks_probe

In function probe(), it returns directly without unregistered hws

when error occurs.

Fix this by adding 'goto unregister_hws;' on line 295 and

line 310.

Use devm_kzalloc() instead of kzalloc() to automatically

free the memory using devm_kfree() when error occurs.

Replace of_iomap() with devm_of_iomap() to automatically

handle the unused ioremap region and delete 'iounmap(anatop_base);'

in unregister_hws.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
