Executive Summary

This vulnerability in the Linux kernel involves the erofs filesystem, where there was no limit on the level of filesystem stacking for file-backed mounts. This could lead to a kernel stack overflow, for example, if the EROFS filesystem mounts itself recursively.

Impact Analysis

The vulnerability could cause a kernel stack overflow, potentially leading to system instability, crashes, or denial of service on affected Linux systems using the erofs filesystem with file-backed mounts.
