Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The rcubarrier function was called in ksmbdserverexit. The bug is triggered due to racing between closing a connection and the rmmod operation. In ksmbd, rcubarrier is not called at the time of module unloading, so nothing...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: smb: client: fix double-free of TCPServerInfo::hostname When shutting down the server in cifsputtcpsession, the cifsd thread might reconnect to multiple DFS targets before realizing that it should exit the loop. As a result,...

Astra Linux – Vulnerability in curl

In some cases, curl may reuse the wrong connection for SMB transfers. curl features a pool of recent connections, so subsequent requests can reuse an existing connection to avoid additional overhead. When reusing a connection, a set of criteria must be met. Due to a logical error in the code, a...

Astra Linux – Vulnerability in Linux 6.1

A out-of-bounds read vulnerability was discovered in smb2dumpdetail in the fs/smb/client/smb2ops.c file within the Linux kernel. This issue could allow a local attacker to crash the system or leak internal kernel information...

CVE-2026-68388

CVE-2026-68388 (Linux kernel SMB client): The smb3_simple_fallocate_range() path can mis-handle allocated ranges returned by the server, causing holes to be skipped and writes to fail with ENOSPC. The issue arises when a server-provided allocated range overlaps the current fallocate offset and st...

EUVD-2026-55444

In the Linux kernel, the following vulnerability has been resolved: smb: client: validate DFS referral PathConsumed parsedfsreferrals validates that the response contains the fixed referral entry array and, on for-next, the per-referral string offsets. However, the response also contains a...

CVE-2026-54206

Tobit Laboratories AG TeamDavid's Webbox 's sending email, fax, SMS, etc. functionality accepts a @@INCLUDE command, which can be set to network locations using UNC paths e.g., “\Server\Share”. The server processes these paths without validation, resulting in outbound connection attempts to...

CVE-2026-54204

Tobit Laboratories AG TeamDavid's Webbox 's search functionality accepts a “pathnameroot” parameter, which can be set to network locations using UNC paths e.g., “\Server\Share”. The server processes these paths without validation, resulting in outbound connection attempts to attacker-controlled...

EUVD-2026-54450

Tobit Laboratories AG TeamDavid's Webbox 's link storing functionality //ServerClientcelink.htm accepts a “pathname” parameter, which can be set to network locations using UNC paths e.g., “\Server\Share”. The server processes these paths without validation, resulting in outbound connection...

EUVD-2026-54438

Tobit Laboratories AG TeamDavid's Webbox 's move archive functionality “!ArcEntryMove” accepts an arbitrary path, which can be set to network locations using UNC paths e.g., “\Server\Share”. The server processes these paths without validation, resulting in outbound connection attempts to...

CVE-2026-54207

CVE-2026-54207 affects Tobit TeamDavid’s Webbox move-archive feature (ArcEntryMove). The function accepts an arbitrary path, including UNC network paths like \Server\Share, which the server processes without validation. This can trigger outbound connections to attacker-controlled SMB servers, all...

SUSE CVE-2026-64597

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double-free in SMB2close replay A response-bearing attempt can return a replayable error and free its response buffer. If SMB2closeinit fails before the next send, cleanup retains the previous buffer type and fre...

CVE-2026-64578

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB3 server. A remote attacker could exploit this vulnerability by crafting a malicious compound SMB2 request. This improper validation of the request size before reading specific data could lead to an out-of-bounds read,...
