CVE-2023-39176

A flaw was found within the parsing of SMB2 requests that have a transform header in the kernel ksmbd module. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this to disclose...

The vulnerability of the ksmbdexpiresession() function in the implementation of the SMB (Server Message Block) network protocol within the kernel of the CIFS/SMB3-server ksmbd in Linux operating systems allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the ksmbdexpiresession function in the fs/smb/server/mgmt/usersession.c module, which is part of the SMB Server Message Block networking implementation within the Linux-based ksmbd CIFS/SMB3 server, relates to the reutilization of previously freed memory due to competitive...

Linux Kernel ksmbd Session Race Condition Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. Authentication is required to exploit this vulnerability. However, only systems with ksmbd enabled are vulnerable. The specific flaw exists within the implementation of session setup an...

PT-2024-34110

The Linux kernel's ksmbd component is affected by a memory exhaustion issue due to simultaneous SMB operations, which can consume excessive memory through the "ksmbd work cache", leading to an Out-of-Memory OOM issue. The issue arises when a client sends multiple SMB operations to ksmbd, and the...
