MediumCVSS 5.5/10Last modified Oct 30, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Pass non-null to dcn20_validate_apply_pipe_split_flags

[WHAT & HOW] "dcn20_validate_apply_pipe_split_flags" dereferences merge, and thus it cannot be a null pointer. Let's pass a valid pointer to avoid null dereference.

This fixes 2 FORWARD_NULL issues reported by Coverity.
