CVE-2023-32257

Published: 24 July 2023

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_SESSION_SETUP and SMB2_LOGOFF 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.

From the Ubuntu Security Team

Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Notes

AuthorNote
rodrigo-zaiden
also kwnon as ZDI-23-705, ZDI-CAN-20596
needs ksmbd-tools installed to enable the service, which is
not installed by default.
same fix as CVE-2023-32252, CVE-2023-32250
