CVE-2026-97917 Linux CVE debrief

Who should care

Linux kernel maintainers, administrators, and users of systems with the affected kernel version should assess exposure and apply patches or mitigations as available. The vulnerability affects the accel/ivpu component of the Linux kernel, and those responsible for maintaining and securing Linux kernel installations should take action to verify and apply kernel updates.

Why it matters

CVE-2026-97917 is a vulnerability in the Linux kernel's accel/ivpu component that requires validation of memory ranges to prevent potential security issues. Linux kernel maintainers, administrators, and users should assess exposure and apply patches or mitigations as available.

• Verify memory range validation in accel/ivpu component
• Assess and apply kernel updates to prevent potential security issues
• Monitor system logs for unusual activity related to memory operations

Technical summary

The Linux kernel's accel/ivpu component has a vulnerability related to improper validation of the full buffer range in the ivpu_to_cpu_addr function. This issue has been resolved with a patch that adds a size parameter to the function and validates the memory range. The patch ensures that the whole [vpu_addr, vpu_addr + size) range stays within the BO, preventing potential security issues. The vulnerability could allow for undefined behavior or security issues when handling specific memory operations. Linux kernel maintainers, administrators, and users of systems with the affected kernel version should assess exposure and apply patches or mitigations as available.

Defensive priority

Assess and apply kernel updates to ensure the accel/ivpu component properly validates memory ranges.

Recommended defensive actions

• Assess exposure of Linux kernel installations to CVE-2026-97917
• Verify and apply kernel updates for the accel/ivpu component
• Monitor system logs for unusual activity related to memory operations
• 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 vulnerability but do not specify versions, exploitation, impact, or remediation. Further verification is required from official sources. The Linux kernel patch adds a size parameter to ivpu_to_cpu_addr() and validates that the whole [vpu_addr, vpu_addr + size) range stays within the BO. The accel/ivpu component did not properly validate the full buffer range, which could lead to security issues. The patch has been applied to resolve the vulnerability.
