{"apiVersion":"1.0","identifier":"CVE-2026-68464","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.","publishedAt":"2026-08-15T06:19:25","lastModifiedAt":"2026-08-17T06:17:55","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-68464","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00166,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-68464","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-68464","en":"https://www.redsauce.net/en/cves/CVE-2026-68464","fr":"https://www.redsauce.net/fr/cves/CVE-2026-68464","pt":"https://www.redsauce.net/pt/cves/CVE-2026-68464","de":"https://www.redsauce.net/de/cves/CVE-2026-68464","sk":"https://www.redsauce.net/sk/cves/CVE-2026-68464","el":"https://www.redsauce.net/el/cves/CVE-2026-68464"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-68464"}}
