CVE-2024-49990 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/xe/hdcp: Check GSC structure validity Sometimes xe_gsc is not initialized when checked at HDCP capability check. Add gsc structure check to avoid null pointer error.
A vulnerability in the Linux kernel's handling of HDCP (High-bandwidth Digital Content Protection) capabilities has been addressed. The issue arose in the DRM (Direct Rendering Manager) XE subsystem, where the GSC (Graphics Stream Control) structure was sometimes uninitialized during HDCP capability checks. This oversight could lead to null pointer dereferences. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been fixed.
