In the Linux kernel, the following vulnerability has been resolved: smb: client: fix overflow in passthrough ioctl bounds check smb2ioctlqueryinfo validates the PASSTHRUFSCTL response payload before copying it to userspace. The payload offset and length both come from 32-bit fields. The bounds...
CVE-2026-68457
CVE-2026-68457 affects the Linux kernel ksmbd: FSCTL mutations (SET_SPARSE, SET_ZERO_DATA, SET_COMPRESSION) on an open SMB handle. The vulnerability arises because these operations call VFS helpers (xattr, fallocate, fileattr) using the current ksmbd worker credentials, which can revalidate inode...
CVE-2026-68457 ksmbd: use opener credentials for FSCTL mutations
In the Linux kernel, the following vulnerability has been resolved: ksmbd: use opener credentials for FSCTL mutations SETSPARSE, SETZERODATA and SETCOMPRESSION operate on an open SMB handle but call VFS xattr, fallocate or fileattr helpers with the current ksmbd worker credentials. Those helpers...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the ksmbd module, the SET SPARSE, SET ZERO DATA, and SET COMPRESSION operations use current worker credentials instead of the credentials captured when the SMB handle was opened. This...
Linux Distros Unpatched Vulnerability : CVE-2026-68457
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ksmbd: use opener credentials for FSCTL mutations SETSPARSE, SETZERODATA and SETCOMPRESSION operate on an open SMB handle but call VFS xattr, fallocate or...
Directory Traversal
Spring Integration is vulnerable to Directory Traversal. The vulnerability is due to insufficient validation of file paths received from malicious or compromised FTP/SFTP/SMB servers, which allows an attacker to write arbitrary content to files outside the configured local directory...
The vulnerability in the `fs/smb/server/server.c` component of the Linux operating system allows a hacker to cause a service failure.
The vulnerability in the fs/smb/server/server.c component of the Linux operating system is related to the execution of a loop with an unreachable exit condition. Exploiting this vulnerability can allow an attacker to cause a service failure...
The vulnerability of the ksmbd component in the Linux operating system’s kernel allows a hacker to trigger a service failure.
The vulnerability of the ksmbd component in the Linux operating system’s kernel is related to the lack of data security mechanisms. Exploiting this vulnerability can allow an attacker to cause service failures...
CVE-2026-64597
A flaw was found in the Linux kernel's Server Message Block SMB client. A vulnerability exists in the SMB2close replay mechanism where a response buffer can be freed twice. This double-free condition can lead to memory corruption, potentially resulting in a denial of service or the execution of...
The vulnerability of the smb/server/smb2pdu.c component in the Linux operating system allows a hacker to trigger a service failure.
The vulnerability of the smb/server/smb2pdu.c component in the Linux operating system is related to the failure to release resources after their useful lifespan has ended. Exploiting this vulnerability can allow an attacker to cause service failures...

CVE-2026-68431
The CVE-2026-68431 entry documents a Linux kernel ksmbd flaw where SMB2 transform requests bypass minimum PDU size validation, allowing an unauthenticated remote attacker on SMB2.1 to trigger reads beyond the request allocation and potentially disclose data. The issue arises because the transform...

CVE-2026-68099
A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB server. An integer overflow vulnerability exists when processing Access Control Lists ACLs. This flaw can lead to a malformed ACL, which, when re-parsed by clients or ksmbd itself, may trigger out-of-bounds reads. Thi...
CVE-2026-68343
A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System DFS referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds...
