Frequently Asked Questions
What is CVE-2024-1023?
A vulnerability in the Eclipse Vert.x toolkit results in a memory leak due to using Netty FastThreadLocal data structures. Specifically, when the Vert.x HTTP client establishes connections to different hosts, triggering the memory leak. The leak can be accelerated with intimate runtime knowledge, allowing an attacker to exploit this vulnerability. For instance, a server accepting arbitrary internet addresses could serve as an attack vector by connecting to these addresses, thereby accelerating the memory leak.
Is CVE-2024-1023 actively exploited?
No confirmed active exploitation of CVE-2024-1023 has been reported, but organizations should still patch proactively.
How to fix CVE-2024-1023?
No patch is currently available. Monitor vendor advisories for updates.
What is the CVSS score for CVE-2024-1023?
CVE-2024-1023 has a CVSS v3.1 base score of 6.5 (MEDIUM).

Weaknesses (CWE)
CWE-401 — Missing Release of Memory after Effective Lifetime: The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
- [Implementation] Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone. For example, glibc in Linux provides protection against free of invalid pointers. When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391]. To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
- [Architecture and Design] Use an abstraction library to abstract away risky APIs. Not a complete solution.
