Description OSIDB Bzimport 2024-09-18 08:22:43 UTC

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.
