Solution
Implement lock bit protection for NBIO registers to prevent unauthorized SMN access and code execution.
  • Ensure lock bit protection is enabled for NBIO registers.
  • Apply vendor-provided security updates or patches.
  • Restrict administrative privileges to authorized personnel.
  • Monitor system logs for suspicious activity.
