CVE-2026-68464

Linux kernel

Description

In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-esdhc-imx: disable irq during suspend to fix unhandled interrupt When using WIFI out-of-band wakeup, an -irq xxx: nobody cared- warning occurs. This happens because the usdhc interrupt is not disabled during system suspend when device_may_wakeup() returns false. The sequence of events leading to this issue: 1. System enters suspend without disabling usdhc interrupt (because device_may_wakeup() returns false for usdhc device) 2. WIFI out-of-band wakeup triggers system resume via GPIO interrupt 3. WIFI sends a Card interrupt before usdhc has fully resumed 4. usdhc is still in runtime suspend state and cannot handle the interrupt properly 5. The unhandled interrupt triggers -nobody cared- warning Fix this by unconditionally disabling the usdhc interrupt during suspend and re-enabling it during resume, regardless of the wakeup capability. This ensures no interrupts are processed during the suspend/resume transition.
