CVE-2026-93824 Linux CVE debrief

Who should care

Linux administrators and security teams should assess their kernel configurations for TLS and sockmap usage, ensuring these are not combined, and monitor for updates from Linux. This update affects Linux administrators and security teams, requiring assessment of kernel configurations and monitoring for updates. The rejection of TLS and sockmap combination in the Linux kernel affects users who manage Linux systems, particularly those responsible for kernel

Why it matters

The Linux kernel update rejecting TLS and sockmap combination affects Linux administrators and security teams, requiring assessment of kernel configurations and monitoring for updates.

• Verify Linux kernel configurations to prevent combining TLS and sockmap
• Assess sockmap and TLS configurations for potential security risks
• Monitor Linux updates for related patches and advisories

Technical summary

The Linux kernel now rejects combining TLS and sockmap due to latent bugs. This change prevents adding TLS sockets to sockmaps and configuring TLS keys in such setups, addressing potential security risks. The update is based on the minimal usage of this integration and the potential for exploitable bugs. Linux administrators and security teams should assess their kernel configurations for TLS and sockmap usage, ensuring these are not combined, and monitor for updates from Linux. This change is a preventive measure to minimize potential security risks.

Defensive priority

Assess Linux kernel configurations for TLS and sockmap usage, verify sockmap and TLS configurations are not combined, and monitor for related updates from Linux.

Recommended defensive actions

• Assess Linux kernel configurations for TLS and sockmap usage
• Verify sockmap and TLS configurations are not combined
• Monitor for related updates from Linux
• Review compensating controls for exposed systems while remediation is scheduled and verified
• 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

Evidence notes

The CVE record and NVD entry provide details on the Linux kernel update rejecting TLS and sockmap combination. References include links to specific kernel patches. The integration of TLS and sockmap in the Linux kernel has been rejected due to the presence of latent bugs that could be exploited. This rejection aims to minimize potential security risks associated with this uncommonly used integration. Linux administrators and security teams should verify their kernel configurations to prevent combining TLS and sockmap and monitor for
