In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: pl353: fix probe resource allocation
During probe(), the devm_ioremap() is called with the parent device
instead of the current one. So when the module is unloaded, the register
area isn't released.
Target the pl35x device in the devm_ioremap() instead of its parent.
A flaw was found in the mtd: rawnand: pl353 component of the Linux kernel. During the probe function, the devm_ioremap() call incorrectly uses the parent device instead of the pl35x device for resource allocation. This oversight prevents the register area from being properly released when the module is unloaded. A local attacker could potentially exploit this to cause a resource leak, leading to a denial of service (DoS) over time.
