Summaryinfo

A vulnerability identified as critical has been detected in libnbd. This issue affects some unknown processing of the component Uniform Resource Identifier Handler.

Detailsinfo

A vulnerability was found in libnbd (affected version not known). It has been classified as critical. This affects some unknown functionality of the component Uniform Resource Identifier Handler. The manipulation with an unknown input leads to a argument injection vulnerability. CWE is classifying the issue as CWE-88. The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A flaw was found in libnbd. A malicious actor could exploit this by convincing libnbd to open a specially crafted Uniform Resource Identifier (URI). This vulnerability arises because non-standard hostnames starting with '-o' are incorrectly interpreted as arguments to the Secure Shell (SSH) process, rather than as hostnames. This could lead to arbitrary code execution with the privileges of the user running libnbd.

The advisory is shared at access.redhat.com. This vulnerability is uniquely identified as CVE-2025-14946 since 12/19/2025. The exploitability is told to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059 for this issue.
