Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: Check for tg ops in dce110_set_avmute<br />
<br />
Some older DCE timing generators do not implement is_tg_enabled in<br />
their ops table. Calling it unconditionally when waiting for AV mute<br />
frames causes a NULL pointer dereference on Southern Islands dGPUs<br />
when turning the display off over HDMI.<br />
<br />
Check that tg and the required ops exist before waiting for frames.<br />
<br />
(cherry picked from commit 2686a0c0aaa07bec2e24131835cf27b5fd4935a5)
