The vulnerability of the `ksmbd_session_rpc_open()` function in the `fs/smb/server/mgmt/user_session.c` module of the SMB server support in Linux operating systems allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ksmbdsessionrpcopen function in the fs/smb/server/mgmt/usersession.c module, which is part of the SMB server support in Linux operating systems, relates to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise th...

CVE-2025-71204

A reference count leak flaw was found in the Linux kernel's ksmbd in-kernel SMB server. In the parsedurablehandlecontext function, when a command is detected as a replay operation and returns -ENOEXEC, the reference count of the ksmbdfile structure is not properly released. This leads to a resour...
