AI-suggested
A patch is available that corrects the resource allocation in the mtd:rawnand:pl353 driver by properly targeting the pl35x device in devm_ioremap(). Users should apply the official Linux kernel updates that include this fix. No additional mitigation steps are indicated by the vendor advisory.
Description
A resource allocation issue in the Linux kernel's mtd:rawnand:pl353 driver was fixed. The vulnerability involved incorrect use of devm_ioremap() during device probe, which caused the register area not to be released upon module unload. This could lead to resource leaks. The issue has been addressed by targeting the correct device in the devm_ioremap() call.
