Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: set new_stream to NULL after release<br />
<br />
In dm_update_crtc_state(), the skip_modeset path releases new_stream<br />
via dc_stream_release() but does not set the pointer to NULL.<br />
<br />
If a later error (e.g., color management failure) triggers the fail<br />
label, the error path calls dc_stream_release() again on the same<br />
dangling pointer, causing a double release and potential use-after-free.<br />
<br />
Fix this by setting new_stream to NULL after the initial release.<br />
<br />
