File Interface Vulnerability in Linux Kernel by The Linux Foundation

CVE-2022-49705

Summary

A vulnerability in the Linux kernel's 9p filesystem implementation can lead to a file identifier (fid) reference count leak during the atomic open process. This occurs when the system fails midway through the open operation, leaving the directory fid unreleased. The issue has been identified and resolved to prevent further fid leaks, ensuring improved stability and security in file operations within affected Linux environments.
