CVE ID :CVE-2026-43988
Published : May 26, 2026, 10:16 p.m. | 44 minutes ago
Description :Vanetza is an open-source implementation of the ETSI C-ITS protocol suite. In 26.02 and earlier, a denial-of-service vulnerability was identified in the ASN.1/OER parsing pipeline of Vanetza. When processing malformed network packets containing corrupted ASN.1/OER structures (e.g., invalid length fields or malformed certificate encoding), the ASN.1 wrapper (asn1c_wrapper.cpp) raises a std::runtime_error. This exception is not caught at the parsing boundary and propagates to std::terminate, resulting in process termination. This vulnerability is fixed with commit 62dfe58a8342512b6e1947d75821402ada524f1a.
Severity: 7.5 | HIGH
