**Name of the Vulnerable Software and Affected Versions** Amazon AWS Firecracker versions 0.21.3 and earlier, 0.22.x before 0.22.1 **Description** The issue is related to the serial console buffer, which can grow its memory usage without limit when data is sent to the standard input. This can result in a memory leak on the microVM emulation thread, possibly occupying more memory than intended on the host. **Recommendations** For Amazon AWS Firecracker versions 0.21.3 and earlier, update to version 0.21.3 or later. For Amazon AWS Firecracker versions 0.22.x before 0.22.1, update to version 0.22.1 or later.
