CVE-2026-81574 Format String Vulnerability in Logger

In CodeMeter Runtime before versions 8.41a and 9.10, the logger does not sanitize input strings in certain cases, allowing an attacker to inject printf-style format specifiers. This can be used to reliably crash CodeMeter and disclose sensitive information such as process memory and stack canarie...

CVE-2026-81574

CodeMeter Runtime versions prior to 8.41a and 9.10 are affected by a format string vulnerability in the logger component, which fails to sanitize input strings in certain cases, allowing injection of printf-style format specifiers . An attacker can reliably crash CodeMeter and disclose sensitive ...

CVE-2026-81573 Improper Access Control in Local-Only Configuration Commands

If CodeMeter Runtime before 8.41a or 9.10 is configured as a server, the configuration command handler does not enforce network- origin restrictions. Commands intended only for local or same-network clients can therefore be executed by arbitrary remote peers. An attacker can read potentially...

CVE-2026-81573

CodeMeter Runtime versions before 8.41a or 9.10 are affected when configured as a server. The configuration command handler fails to enforce network-origin restrictions, allowing arbitrary remote peers to execute commands intended only for local or same-network clients. This enables reading sensi...

CVE-2026-81572 Local Privilege Escalation in CodeMeter Runtime on Windows

In CodeMeter Runtime from version 8.40 to excluding 8.41a and 9.00 to excluding 9.10, cmu.exe --create-io --file C: creates a predictable temporary file under C:\CM-Stick. The directory and file paths are not properly checked for NTFS reparse points, such as junctions or symbolic links, before fi...

CVE-2026-81572

CodeMeter Runtime (WibuSystems) on Windows is vulnerable to a local privilege escalation via a predictable temporary file. The cmu.exe executable, when invoked with --create-io --file C:, creates a temporary file under C:\CM-Stick without checking the directory and file paths for NTFS reparse poi...

SUSE CVE-2026-74754

In the Linux kernel, the following vulnerability has been resolved: scsi: core: pair EH runtime PM get and put shost-ehnoresume is currently consulted twice in one error handling iteration: once before scsiautopmgethost and once again before scsiautopmputhost. That is racy when a PM-triggered err...

PT-2026-82479

If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 issues handles per connection and relies on a cryptographically weak SID as sole authenticator. An attacker can brute-force the SID, recover another session's handle number, and read license information belonging to anoth...
