How to fix?

Upgrade SLES:16.0.0 kernel-docs-html to version 6.12.0-160000.6.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs-html package and not the kernel-docs-html package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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.
