CVE-2025-38467

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: exynos7_drm_decon: add vblank check in IRQ handling If there's support for another console device (such as a TTY serial), the kernel occasionally panics during boot. The panic message and a relevant snippet of the call stack is as follows: Unable to handle kernel NULL pointer dereference at virtual address 000000000000000 Call trace: drm_crtc_handle_vblank+0x10/0x30 (P) decon_irq_handler+0x88/0xb4 [...] Otherwise, the panics don't happen. This indicates that it's some sort of race condition. Add a check to validate if the drm device can handle vblanks before calling drm_crtc_handle_vblank() to avoid this.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/exynos: exynos7_drm_decon: añadir comprobación de vblank en el manejo de IRQ Si hay soporte para otro dispositivo de consola (como un serial TTY), el kernel ocasionalmente entra en pánico durante el arranque. El mensaje de pánico y un fragmento relevante de la pila de llamadas es el siguiente: Unable to handle kernel NULL pointer dereference at virtual address 000000000000000 Rastreo de llamada: drm_crtc_handle_vblank+0x10/0x30 (P) decon_irq_handler+0x88/0xb4 [...] De lo contrario, los pánicos no ocurren. Esto indica que es algún tipo de condición de ejecución. Agregue una comprobación para validar si el dispositivo drm puede manejar vblanks antes de llamar a drm_crtc_handle_vblank() para evitar esto.
