CVE-2023-32258: Linux Kernel ksmbd Session Race Condition Remote Code Execution Vulnerability
First published: Wed Jul 05 2023(Updated: )
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_LOGOFF and SMB2_CLOSE commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.
