Description OSIDB Bzimport 2025-09-16 09:03:36 UTC 
In the Linux kernel, the following vulnerability has been resolved:

clk: imx: clk-imxrt1050: fix memory leak in imxrt1050_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().

Also, fix error handling of hws by adding unregister_hws label, which
unregisters remaining hws when iomap failed.
