CVE-2026-46216

The CVE-2026-46216 issue affects the Linux kernel drm/xe/hdcp module. When media GT is disabled via configfs, media_gt may be NULL, causing intel_hdcp_gsc_check_status() to dereference an invalid address and trigger a kernel pagefault. The fix adds a NULL check on media_gt and returns early if NU...

CVE-2026-46149 scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show()
