Upgrade affected software to a fixed version, for example Arm 5th Gen Gpu Architecture Kernel Driver r43p0, Arm Bifrost Gpu Kernel Driver r43p0, Arm Valhall Gpu Kernel Driver r43p0 or later, then confirm no affected versions remain in your inventory.

How Secuno handles this

Secuno correlates vulnerabilities like CVE-2023-26083 against the real software inventory on every managed device, as each hourly inventory arrives. Rather than a static severity, each match is scored in context: exploit availability, EPSS, the asset's exposure, and business criticality decide where it lands in the queue. Because it is on the CISA KEV list, a risk for it never ranks below high, and the update that fixes it moves to the Emergency patch lane. If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
