CVE-2023-32251: Red Hat Enterprise Linux 10

Low severity, CVSS 3.7. EPSS: 0.5% chance of exploitation in the next 30 days.

A vulnerability has been identified in the Linux kernel's ksmbd component (kernel SMB/CIFS server). A security control designed to prevent dictionary attacks, which introduces a 5-second delay during session setup, can be bypassed through the use of asynchronous requests. This bypass negates the intended anti-brute-force protection, potentially allowing attackers to conduct dictionary attacks more efficiently against user credentials or other authentication mechanisms.
