CVE-2026-97592 Linux CVE debrief

Who should care

Linux kernel maintainers, users, and administrators should assess exposure and verify patched versions. It is recommended to review kernel logs for suspicious activity and verify patched Linux kernel versions. Linux kernel maintainers and users should verify patched versions and assess exposure to prevent potential data exposure.

Why it matters

A vulnerability in the Linux kernel's s390/crypto implementation could lead to exposure of sensitive data. Linux kernel maintainers and users should verify patched versions and assess exposure.

• Verify patched Linux kernel versions to prevent potential data exposure
• Assess exposure in s390/crypto implementations to prevent potential data exposure

Technical summary

The Linux kernel's s390/crypto implementation has a vulnerability that could lead to exposure of sensitive data. The vulnerability is related to the AES ctr and gcm algorithms, and Linux kernel maintainers and users should verify patched versions and assess exposure. This vulnerability affects the s390/crypto implementation, and it is recommended to review kernel logs for suspicious activity and verify patched Linux kernel versions. The vulnerability could lead to exposure of sensitive data if not patched properly.

Defensive priority

Linux kernel maintainers and users should verify patched versions and assess exposure.

Recommended defensive actions

• Verify patched Linux kernel versions
• Assess exposure in s390/crypto implementations
• Review kernel logs for suspicious activity
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
