Descriptions

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.

Se encontró una falla en el ksmbd del kernel de Linux, un servidor SMB de alto rendimiento en el kernel. La falla específica existe dentro del procesamiento de comandos SMB2_LOGOFF y SMB2_CLOSE. El problema se debe a la falta de bloqueo adecuado al realizar operaciones en un objeto. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del kernel.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability, but only systems with ksmbd enabled are vulnerable.
