CVE-2026-0968
LowCVSS 3.1Exploitation Probability (EPSS)
Low risk37th percentile - higher than 37% of all known CVEs
Summary
A flaw was found in libssh in which a malicious SFTP server can exploit this by sending a malformed 'longname' field within an `SSH_FXP_NAME` message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap, causing unexpected behavior or denial of service (DoS) due to application crashes.
Risk Assessment
The risk includes the possibility of application crashes and denial of service, which may disrupt systems using libssh.
Recommendation
It is recommended to update libssh to a patched version and monitor SFTP messages for malformed fields.
