Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()<br />
<br />
When media GT is disabled via configfs, there is no allocation for<br />
media_gt, which is kept as NULL. In such scenario,<br />
intel_hdcp_gsc_check_status() results in a kernel pagefault error due to<br />
&gt->uc.gsc being evaluated as an invalid memory address.<br />
<br />
Fix that by introducing a NULL check on media_gt and bailing out early<br />
if so.<br />
<br />
While at it, also drop the NULL check for gsc, since it can&#39;t be NULL if<br />
media_gt is not NULL.<br />
<br />
v2:<br />
- Get address for gsc only after checking that gt is not NULL.<br />
(Shuicheng)<br />
- Drop the NULL check for gsc. (Shuicheng)<br />
v3:<br />
- Add "Fixes" and "Cc: " tags. (Matt)<br />
<br />
(cherry picked from commit bfaf87e84ca3ca3f6e275f9ae56da47a8b55ffd1)
