CVE-2026-0968: The libssh Heap Read That Isn't as Scary as Scanners Say
A missing null check in libssh’s SFTP directory listing code lets a malicious server crash clients, but real-world exploitability is extremely constrained. CVE-2026-0968 is an out-of-bounds heap read in sftp_parse_longname(), triggered when an SFTP client processes a crafted SSH_FXP_NAME response with a malformed longname field. Red Hat, which serves as the CNA (CVE Numbering Authority) for this vulnerability, scored it 3.1 (Low), while Amazon Linux independently scored it 4.2 (Medium).
