          "details": "CVE-2025-13151 involves a one‑byte, stack-based overflow in libtasn1’s asn1_expand_octet_string helper that is only reachable when a program explicitly expands an OCTET STRING using attacker‑supplied ASN.1 and a very specific, high‑complexity condition (two internal definition names both at their maximum lengths). Given the CVSS indicates availability impact only (no confidentiality or integrity) and exploitation requires this narrow code path, the practical risk to typical server/VM workloads is limited to potential process crashes. As a result, it can be safely deprioritized relative to vulnerabilities that enable data disclosure or code execution.",
