Descriptions
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_TREE_CONNECT and SMB2_QUERY_INFO commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.
Se ha encontrado un fallo en el ksmbd del kernel de Linux, un servidor SMB de alto rendimiento integrado en el kernel. El fallo específico existe en el manejo de los comandos SMB2_TREE_CONNECT y SMB2_QUERY_INFO. El problema se debe a la falta de validación adecuada de un puntero antes de acceder a él. Un atacante puede aprovechar esta vulnerabilidad para crear una condición de denegación de servicio en el sistema.
This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability, but only systems with ksmbd enabled are vulnerable.
