CVE-2026-46216

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 /> &amp;gt-&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&amp;#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)
