About this tag
The smb cifs tag on WindowsForum.com covers discussions about the Server Message Block (SMB) and Common Internet File System (CIFS) protocols, particularly in the context of Linux kernel vulnerabilities. Recent threads highlight critical security issues such as CVE-2024-0565, an integer-underflow bug in the Linux SMB/CIFS client that can lead to out-of-bounds memory reads and potential remote code execution, and CVE-2024-35869, a use-after-free defect affecting DFS referrals and failover operations. These posts provide patch guides and mitigation advice for system administrators managing Linux hosts that mount SMB/CIFS shares. The tag focuses on security advisories, kernel-level bugs, and practical steps to secure SMB/CIFS implementations.

  1. CVE-2024-0565 Critical Linux SMB/CIFS Kernel Vulnerability

    A critical robustness bug in the Linux kernel’s SMB/CIFS client—tracked as CVE-2024-0565—creates an integer-underflow condition in the function receive_encrypted_standard that can lead to out‑of‑bounds memory reads, denial-of-service, and in some vendor assessments the potential for remote code...
