CVE-2026-46216 drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()

In the Linux kernel, the following vulnerability has been resolved: drm/xe/hdcp: Add NULL check for mediagt in intelhdcpgsccheckstatus When media GT is disabled via configfs, there is no allocation for mediagt, which is kept as NULL. In such scenario, intelhdcpgsccheckstatus results in a kernel...

CVE-2026-46194

CVE-2026-46194 is a Linux kernel/f2fs race condition where f2fs_destroy_extent_node() clears extent nodes without FI_NO_EXTENT, allowing concurrent writeback to insert nodes and trigger a bug check. The issue arises when dropping inodes with I_SYNC during writeback, leading to a potential crash/D...
