CVE-2026-97414 Linux CVE debrief

Who should care

Linux kernel developers and maintainers, as well as users of affected Linux distributions, should assess exposure and verify remediation to address potential system crashes or instability due to NULL pointer dereferences. This includes reviewing and applying patches, verifying Linux kernel versions, and monitoring system logs for errors.

Why it matters

This vulnerability in the Linux kernel's ASoC: mediatek mt8365-afe-pcm component could lead to system crashes or instability if exploited. Linux kernel developers and maintainers, as well as users of affected Linux distributions, should assess exposure and verify remediation.

• Potential system crashes or instability due to NULL pointer dereferences
• Need for verification of Linux kernel version and patch application
• Potential for denial-of-service (DoS) attacks if exploited

Technical summary

The mt8365_afe_suspend() function in the Linux kernel's ASoC: mediatek mt8365-afe-pcm component allocates a register backup buffer using devm_kcalloc() but does not check for allocation failure before using the returned pointer. This may lead to a NULL pointer dereference when accessing afe->reg_back_up[i]. The vulnerability could lead to system crashes or instability if exploited, emphasizing the need for verification of Linux kernel version and patch application, as well as monitoring system logs for potential NULL pointer dereference errors.

Defensive priority

Medium

Recommended defensive actions

• Review and apply the provided patches to address the vulnerability
• Verify the Linux kernel version and ensure it is up-to-date
• Monitor system logs for potential NULL pointer dereference errors
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes
