AI-suggested

Official patches are available from Red Hat for affected libssh versions in Red Hat Enterprise Linux 9 and 10. Users should apply the updated libssh packages as described in Red Hat advisories RHSA-2025:18231 and RHSA-2025:18275. For detailed update instructions, refer to https://access.redhat.com/articles/11258. Applying these updates fully mitigates the vulnerability.

Description

A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
