4DescriptionCVE.org
A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service (DoS) by causing the system to try and access dangerous files, such as block devices or large system files, which can disrupt normal operations.
AnalysisAI
libssh attempts to open arbitrary files during configuration parsing, allowing local attackers with limited privileges to trigger a denial of service by forcing access to dangerous files such as block devices or large system files. The vulnerability affects Red Hat Enterprise Linux versions 6, 7, 8, 9, and 10, as well as Red Hat OpenShift Container Platform 4, and requires local access with low privileges to exploit. No public exploit code or active exploitation has been confirmed at the time of analysis.
Technical ContextAI
The vulnerability exists in libssh, an SSH protocol library commonly used in Red Hat Enterprise Linux distributions and containerized environments. The flaw is classified under CWE-73 (External Control of File Name or Path), which indicates improper validation of file paths during configuration parsing. When libssh processes configuration files, it fails to properly restrict which files may be opened, potentially allowing an attacker to specify paths to sensitive system resources. The affected products are identified via CPE strings spanning Red Hat Enterprise Linux 6 through 10 and Red Hat OpenShift Container Platform 4, indicating the vulnerability impacts both legacy and current supported enterprise distributions.
RemediationAI
Apply the latest security updates provided by Red Hat for affected systems; consult the vendor advisory at https://access.redhat.com/security/cve/CVE-2026-0965 for specific patched package versions corresponding to each RHEL release and OpenShift version. Until patches can be deployed, restrict local user access to systems where SSH configuration is sensitive, enforce restrictive file permissions on SSH configuration directories to prevent unprivileged users from modifying configuration files, and consider disabling or limiting local shell access where operationally feasible. Monitor system logs for unusual SSH service behavior or access attempts to system devices that may indicate exploitation attempts.
