CVE-2025-14946

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.

This vulnerability is rated Moderate for Red Hat because it requires a malicious actor to convince libnbd to open a specially crafted URI. This leads to arbitrary code execution due to improper handling of non-standard hostnames starting with '-o' as SSH arguments, executing code with the privileges of the user running libnbd.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, ensure that applications utilizing libnbd do not process Uniform Resource Identifiers (URIs) from untrusted or unverified sources. This vulnerability requires a malicious actor to convince libnbd to open a specially crafted URI, therefore restricting the sources of URIs processed by libnbd can reduce exposure.
