Last modified

CVE-2023-53249 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe Use devm_of_iomap() instead of of_iomap() to automatically handle the unused ioremap region. If any error occurs, regions allocated by kzalloc() will leak, but using devm_kzalloc() instead will automatically free the memory using devm_kfree().. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
