exfat filesystem

About this tag
The exfat filesystem tag covers discussions about the exFAT file system implementation in Linux, including kernel patches and security vulnerabilities. A recent thread focuses on CVE-2025-38692, a Linux kernel patch that adds a cluster chain loop check for directories to prevent infinite loops caused by on-disk corruption. The thread also examines Microsoft's attestation regarding Azure Linux's inclusion of the vulnerable open-source library, clarifying that this attestation applies only to Azure Linux and not necessarily to other Microsoft products. Topics include kernel robustness, file system integrity, and security response processes.

  1. CVE-2025-38692: Linux exFAT loop patch and Azure Linux attestation

    The Linux kernel patch that landed this year to “add cluster chain loop check for dir” closes a subtle but practical robustness hole in the in‑kernel exFAT implementation that can cause an infinite loop when presented with certain forms of on‑disk corruption — and while Microsoft’s Security...
