CVE-2023-53704
Published Oct 22, 2025
Modified Apr 15, 2026
Description
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.

Frequently Asked Questions
What is CVE-2023-53704? +
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.
How do I check if I'm vulnerable to CVE-2023-53704? +
