CVE-2025-34450 (GCVE-0-2025-34450)
Vulnerability from nvd – Published: 2025-12-18 21:15 – Updated: 2026-05-14 02:08
VLAI
Title
merbanan/rtl_433 <= 25.02 Stack-based Buffer Overflow
Summary
merbanan/rtl_433 versions up to and including 25.02 and prior to commit 25e47f8 contain a stack-based buffer overflow vulnerability in the function parse_rfraw() located in src/rfraw.c. When processing crafted or excessively large raw RF input data, the application may write beyond the bounds of a stack buffer, resulting in memory corruption or a crash. This vulnerability can be exploited to cause a denial of service and, under certain conditions, may be leveraged for further exploitation depending on the execution environment and available mitigations.
