ECHO-8D11-E996-AA3C Reported (VulDB) stack-based buffer overflow in llvm::StringMap::insert in lib/IR/ValueSymbolTable.cpp (ValueSymbolTable module), reachable only by locally feeding crafted IR/input to LLVM tooling. NVD carries the "disputed" tag and the record notes "The presence of this vulnerability remains uncertain". The LLVM project explains that the reported behavior is outside its documented security scope and is therefore not considered a security vulnerability (LLVM libraries are not a security boundary for untrusted input). Reported against llvm-project 22.1.x; the shipped toolchain is 19.1.7. Debian classifies it as an unimportant issue. No code change required. https://security-tracker.debian.org/tracker/CVE-2026-13573
