  3. CVE-2024-35942
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pmdomain: imx8mp-blk-ctrl: imx8mp_blk: Agregar reloj fdcc al dominio hdmimix Según i.MX8MP RM y HDMI ADD, el reloj fdcc es parte de la IP de verificación hdmi rx que debería no está habilitado para HDMI TX. Pero, en realidad, si el reloj está desactivado antes de la sonda HDMI/LCDIF, LCDIF no obtendrá el reloj de píxeles de HDMI PHY e imprimirá los registros de errores: [CRTC:39:crtc-2] Se agotó el tiempo de espera de vblank ADVERTENCIA: CPU: 2 PID: 9 en drivers/gpu/drm/drm_atomic_helper.c:1634 drm_atomic_helper_wait_for_vblanks.part.0+0x23c/0x260 Agregue el reloj fdcc a los dominios de alimentación LCDIF y HDMI TX para solucionar el problema.
