Technical description

In the Linux kernel, the following vulnerability has been resolved:

pmdomain: imx8mp-blk-ctrl: imx8mp_blk: Add fdcc clock to hdmimix domain

According to i.MX8MP RM and HDMI ADD, the fdcc clock is part of

hdmi rx verification IP that should not enable for HDMI TX.

But actually if the clock is disabled before HDMI/LCDIF probe,

LCDIF will not get pixel clock from HDMI PHY and print the error

logs:

[CRTC:39:crtc-2] vblank wait timed out

WARNING: CPU: 2 PID: 9 at drivers/gpu/drm/drm_atomic_helper.c:1634 drm_atomic_helper_wait_for_vblanks.part.0+0x23c/0x260

Add fdcc clock to LCDIF and HDMI TX power domains to fix the issue.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
