Kernel vulnerability in NXP i.MX93 via fsl-edma module

CVE-2025-38479

Summary

The vulnerability pertains to the fsl-edma module within the Linux kernel on NXP's i.MX93 platform. It is related to the improper handling of IRQ freeing during device removal, which can trigger warnings and potentially lead to kernel crashes. The issue arises specifically when there is no error interrupt (errirq) available on the platform, requiring a conditional check to prevent system instability. This is critical for developers and system integrators using the i.MX93 board for embedded applications.
