A patch is available that fixes this issue by unconditionally disabling the usdhc interrupt during suspend and re-enabling it during resume. Users should apply the official Linux kernel updates that include this fix for the affected versions. No additional mitigation is required beyond applying the patch.
Description
A vulnerability in the Linux kernel's mmc subsystem (sdhci-esdhc-imx driver) causes unhandled interrupt warnings during system suspend and resume when WIFI out-of-band wakeup is used. The issue arises because the usdhc interrupt is not disabled during suspend if the device is not allowed to wake the system, leading to interrupts being received while the device is still suspended. This has been fixed by unconditionally disabling the interrupt during suspend and re-enabling it during resume.
