CVE-2023-53704: clk: imx: clk-imx8mp: improve error handling in imx8mp_clocks_probe()

In the Linux kernel, the following vulnerability has been resolved: clk: imx: clk-imx8mp: improve error handling in imx8mp_clocks_probe() Replace of_iomap() and kzalloc() with devm_of_iomap() and devm_kzalloc() which can automatically release the related memory when the device or driver is removed or unloaded to avoid potential memory leak. In this case, iounmap(anatop_base) in line 427,433 are removed as manual release is not required. Besides, referring to clk-imx8mq.c, check the return code of of_clk_add_hw_provider, if it returns negtive, print error info and unregister hws, which makes the program more robust.

Security readout for executives and security teams

Plain-English summary

This CVE concerns Linux kernel error handling in the i.MX8MP clock driver. The issue could leak memory or leave resources registered during probe failure, driver removal, or unload. The source bundle does not provide CVSS, CWE, or evidence of active exploitation.

Executive priority

Treat this as a targeted kernel maintenance issue, not an emergency based on current evidence. Prioritize normal patch cycles for exposed Linux or embedded systems, especially i.MX8MP platforms, while watching vendor advisories for severity updates.

Technical view

The fix replaces manual resource management with devm_of_iomap() and devm_kzalloc(), removes unnecessary iounmap() calls, checks of_clk_add_hw_provider() failures, logs errors, and unregisters hardware clocks. The affected context is clk-imx8mp in the Linux kernel.

Likely exposure

Exposure appears most relevant to Linux systems using the i.MX8MP clock driver. The source bundle lists Linux kernel versions including 5.6, 5.10.188, 5.15.121, 6.1.39, 6.3.13, 6.4.4, and 6.5 as affected.

Exploitation context

The bundle marks CISA KEV status as false and provides no cited evidence of active exploitation, public exploit code, or weaponized use. The described impact is a potential memory leak and more robust cleanup on error paths.

Researcher notes

The record lacks CVSS, CWE, and detailed exploitability analysis. Assessment should stay tied to the driver context and referenced stable commits. Validate whether affected branches in your environment actually include clk-imx8mp and the vulnerable error-handling paths.

Mitigation direction

  • Check vendor or distribution advisories for patched Linux kernel packages.
  • Update affected kernels to builds containing the referenced stable fixes.
  • Prioritize i.MX8MP-based systems or kernels carrying clk-imx8mp.
  • If patching is delayed, monitor affected systems for resource exhaustion symptoms.
  • Avoid custom backports unless they include all cleanup and error-handling changes.

Validation and detection

  • Inventory Linux kernel versions across embedded and server fleets.
  • Identify systems built for or running i.MX8MP clock driver support.
  • Compare deployed kernel source or packages against referenced stable commits.
  • Confirm vendor advisories map the CVE to your kernel build.
  • Review regression testing for boot, driver probe, unload, and removal paths.
