CVE-2023-53833

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/i915: Fix NULL ptr deref by checking new_crtc_state<br /> <br /> intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn&amp;#39;t<br /> obtained previously with intel_atomic_get_crtc_state, so we must check it<br /> for NULLness here, just as in many other places, where we can&amp;#39;t guarantee<br /> that intel_atomic_get_crtc_state was called.<br /> We are currently getting NULL ptr deref because of that, so this fix was<br /> confirmed to help.<br /> <br /> (cherry picked from commit 1d5b09f8daf859247a1ea65b0d732a24d88980d8)
