Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-51302. PoCs published by extratao.

AI-analyzed exploit summary This repository provides a detailed technical analysis debunking CVE-2026-51302 as an LLM-hallucinated vulnerability. It demonstrates that the claimed root cause (use-after-free in SQLite 3.41 via `exprComputeOperands()`) is impossible due to function non-existence in the affected version and logical inconsistencies in register management.

Description

SQLite 3.41 has a use-after-free vulnerability exists in the expression evaluation logic. The sqlite3ReleaseTempReg function improperly releases temporary register resources, and the subsequent exprComputeOperands function continues to access the already freed register memory. By supplying a malicious SQL statement, a remote attacker can exploit this flaw to cause denial of service, leak sensitive information, or potentially execute arbitrary code on the affected system.
