Vulnerability from github – Published: 2024-10-21 18:30 – Updated: 2025-02-21 15:31

Details

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.

Severity

5.5 (Medium)
