Libssh: libssh: denial of service via improper configuration file handling
CVE-2026-0965 is fixed in 7 products on 1 platform, first by RHSA-2026:18160, released February 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
