CVE-2026-88344

An out-of-bounds read vulnerability exists in the schema lexer of flatcc 4c3b999e.

Impact

An out-of-bounds read vulnerability exists in the schema lexer of flatcc 4c3b999e. When an exact-length FlatBuffers schema buffer ends with a digit, the integer digit-scan loop in lex() advances past the end of the input buffer and dereferences the out-of-bounds pointer. A specially crafted schema can trigger a one-byte heap buffer over-read, resulting in application crash and denial of service.
