CVE-2026-58050

CVE-2026-58050 affects libssh2 up to 1.11.1. The publickey subsystem reads an attacker-controlled 32-bit attribute count and uses it in the allocation num_attrs * sizeof(libssh2_publickey_attribute) without bounds checking. On 32-bit platforms, this multiplication can overflow, producing an under...
