CVE-2026-23424: Linux kernel AMD DNA driver can read beyond buffer
CVE-2026-23424 · published 7 months ago
Summary
The AMD DNA driver in certain Linux kernel versions for AWS and Azure did not correctly verify how much data was in a command buffer, allowing excess data to be processed. This could let an attacker cause the system to crash or run unauthorized code. Update the affected kernel packages to the latest released versions to apply the fix.
What to do
- Update debian linux to version 6.19.8-1.
- Update linux kernel to version 6.19.7.
- Update linux linux to version 3464e751755172ddbb849c1bd92f5f59e95c59a1 or later.
