kernel: smb: client: validate dacloffset before building DACL pointers

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server can exploit this vulnerability on 32-bit systems by providing a crafted dacloffset value. This can cause a pointer wrap, leading to the dereferencing of invalid Discretionary Access Control List DACL fields...

CVE-2026-46216

A flaw was found in the Linux kernel's drm/xe/hdcp module. When media Graphics Translation GT is disabled via configfs, a NULL pointer dereference can occur in the intelhdcpgsccheckstatus function.
