CVE-2024-50213

Estado: ModificadaMedia (5.5)—

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

drm/tests: hdmi: Fix memory leaks in drm_display_mode_from_cea_vic()

modprobe drm_hdmi_state_helper_test and then rmmod it, the following memory leak occurs.

The `mode` allocated in drm_mode_duplicate() called by drm_display_mode_from_cea_vic() is not freed, which cause the memory leak:

Free `mode` by using drm_kunit_display_mode_from_cea_vic() to fix it.
