CVE-2026-51302 is a withdrawn CVE record that was initially described by third-party advisories as a use-after-free in SQLite expression evaluation logic. Subsequent investigation determined that the reported issue was not a real security vulnerability. Independent review found major inconsistencies in the claim, including references to nonexistent or mismatched functions, contradictory version details, and proof-of-concept inputs that did not reproduce any crash or memory corruption. The CVE record was ultimately rejected by its CNA with the determination that it was not a security issue.
