CVE-2026-0966

CVE-2026-0966 affects the libssh library with a buffer underflow in ssh_get_hexa() on invalid input. The issue occurs because ssh_get_hexa() is used by ssh_get_fingerprint_hash() and the deprecated ssh_print_hexa(), and also in gssapi logging. Remote triggering is possible when GSSAPI authenticat...
