  "details" : [ "A flaw was found in the Linux kernel. This vulnerability occurs because the NOC_HDCP clock, which is part of the `pmdomain: imx8mp-blk-ctrl` module, is not consistently enabled. This can disrupt the NoC ADB400 port power down handshake, potentially leading to a system hang. The primary impact is a Denial of Service (DoS), where the system becomes unresponsive." ],
