Detailsinfo

A vulnerability was found in Linux Kernel up to 5.10.187/5.15.120/6.1.38/6.3.12/6.4.3. It has been declared as critical. This vulnerability affects the function imx8mp_clocks_probe of the file clk-imx8mq.c of the component clk. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability was named CVE-2023-53704 since 10/22/2025. Technical details are known, but there is no available exploit.

Upgrading to version 5.10.188, 5.15.121, 6.1.39, 6.3.13 or 6.4.4 eliminates this vulnerability.
