Vulnerability from fkie_nvd - Published: 2024-09-18 08:15 - Updated: 2026-06-17 07:55
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check UnboundedRequestEnabled's value CalculateSwathAndDETConfiguration_params_st's UnboundedRequestEnabled is a pointer (i.e. dml_bool_t *UnboundedRequestEnabled), and thus if (p->UnboundedRequestEnabled) checks its address, not bool value. This fixes 1 REVERSE_INULL issue reported by Coverity.
