How to fix?

Upgrade RHEL:10 libssh-config to version 0:0.12.1-4.hum1 or higher.
This issue was patched in RHSA-2026:42922.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libssh-config package and not the libssh-config package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests.
