What is CVE-2026-64219?
This critical flaw arises from insufficient validation of payload length in the `dc_process_dmub_aux_transfer_async` function. A malicious actor can trigger a stack buffer overflow on Linux kernel systems using `drivers/gpu/drm/amd/display`, potentially leading to code execution. Applying the security patch or updating AMD graphics drivers is strongly advised.
Azərbaycanca: Bu kritik boşluq `dc_process_dmub_aux_transfer_async` funksiyasında payload uzunluğunun düzgün yoxlanılmaması səbəbindən yaranır. Zərərli aktor `drivers/gpu/drm/amd/display` istifadə edən Linux kernel sistemlərində stack buffer overflow yaradaraq kod icrasına nail ola bilər. Təhlükəsizlik yaması tətbiq edilənə qədər AMD qrafik driverlərini yeniləmək tövsiyə olunur.
