If this occurs, the kernel can become unresponsive, effectively denying service to the affected system.", "risk_and_exploitability": "The severity is high due to the potential for a kernel hang. No CVSS score is provided and the exploit probability is not available, but the bug would only be exploitable in a privileged context, such as by a root user or a kernel module that triggers a soft reset.
