In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Disable AFBC support on Mediatek DRM driver Commit c410fa9b07c3… (CVE-2025-68184)
A vulnerability in the Linux kernel's Mediatek DRM driver related to AFBC support on the Mediatek MT8188 platform causes vblank timeouts and rendering issues. The AFBC feature, added by a recent commit, is broken on this specific hardware, leading to kernel warnings and graphical corruption. The issue has been addressed by disabling AFBC support on the affected platform until a proper fix is available upstream.
AI Analysis
Technical Summary
The Linux kernel introduced AFBC (Arm Frame Buffer Compression) support to the Mediatek DRM driver, enabling the 32x8/split/sparse modifier. However, this support is currently broken on the Mediatek MT8188 (Genio 700 EVK platform), causing constant vblank wait timeouts and garbled rendering. Kernel trace logs show warnings related to drm_atomic_helper_wait_for_vblanks. The vulnerability is mitigated by disabling AFBC support on this platform until an upstream fix is implemented.
Potential Impact
The vulnerability causes denial of service in the form of graphical rendering failures and kernel vblank timeout warnings on affected Mediatek hardware. It does not impact confidentiality or integrity but results in high availability impact due to rendering disruptions and kernel warnings.
Mitigation Recommendations
Disabling AFBC support on the Mediatek MT8188 platform is the current mitigation until an official upstream fix is released. No official patch or fix is currently available; users should monitor the vendor's kernel updates for remediation.
