Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper resource management in DRM_IOCTL_MODE_CREATEPROPBLOB when allocating arbitrary-sized property blobs backed by kernel memory. A local user can create property blobs to cause a denial of service.
The issue can lead to unbounded kernel memory consumption and potentially system-wide out-of-memory conditions.
