CVE-2025-38467

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/exynos: exynos7_drm_decon: add vblank check in IRQ handling<br /> <br /> If there&amp;#39;s support for another console device (such as a TTY serial),<br /> the kernel occasionally panics during boot. The panic message and a<br /> relevant snippet of the call stack is as follows:<br /> <br /> Unable to handle kernel NULL pointer dereference at virtual address 000000000000000<br /> Call trace:<br /> drm_crtc_handle_vblank+0x10/0x30 (P)<br /> decon_irq_handler+0x88/0xb4<br /> [...]<br /> <br /> Otherwise, the panics don&amp;#39;t happen. This indicates that it&amp;#39;s some sort<br /> of race condition.<br /> <br /> Add a check to validate if the drm device can handle vblanks before<br /> calling drm_crtc_handle_vblank() to avoid this.
