CVE-2026-2646
Heap buffer overflow in session parsing with wolfSSL_d2i_SSL_SESSION() function
Résumé
Heap buffer overflow in session parsing with wolfSSL_d2i_SSL_SESSION() function
Description d'origine
La description telle que publiée par la source (souvent en anglais).
A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSL_d2i_SSL_SESSION() function. When deserializing session data with SESSION_CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and corrupt heap memory. A maliciously crafted session would need to be loaded from an external source to trigger this vulnerability. Internal sessions were not vulnerable.
