{"id":"CVE-2026-88344","published":"2026-09-22T20:17:10.493","lastModified":"2026-09-24T21:16:28.120","description":"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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/dvidelabs/flatcc/issues/384","tags":[]},{"url":"https://github.com/jimjag/flatcc/commit/c1dcc8ecd1a74b1e9e724ec7dc98828a5c95528e","tags":[]},{"url":"https://github.com/dvidelabs/flatcc/issues/384","tags":[]}],"exploitRefs":[{"url":"https://github.com/dvidelabs/flatcc/issues/384","tags":[]},{"url":"https://github.com/jimjag/flatcc/commit/c1dcc8ecd1a74b1e9e724ec7dc98828a5c95528e","tags":[]},{"url":"https://github.com/dvidelabs/flatcc/issues/384","tags":[]}],"hasPoc":true,"ai":null}
