AnalysisAI
wasm3 commit 7890a2097569fde845881e0b352d813573e371f9 was discovered to contain a segmentation fault via the component op_CallIndirect at /m3_exec.h. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. wasm3 commit 7890a2097569fde845881e0b352d813573e371f9 was discovered to contain a segmentation fault via the component op_CallIndirect at /m3_exec.h. Affected products include: Wasm3 Project Wasm3.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
