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/amd/display: Add null pointer check in mod_hdcp_hdcp1_create_session()

The function mod_hdcp_hdcp1_create_session() calls the function get_first_active_display(), but does not check its return value. The return value is a null pointer if the display list is empty. This will lead to a null pointer dereference.

Add a null pointer check for get_first_active_display() and return MOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null.

This is similar to the commit c3e9826a2202 ("drm/amd/display: Add null pointer check for get_first_active_display()").

(cherry picked from commit 5e43eb3cd731649c4f8b9134f857be62a416c893)
