27 Feb 2026 — In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization (runtime/intern.c) enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock() function, which performs unbounded memcpy() operations using attacker-controlled lengths from crafted Marshal data. En OCaml anterior a 4.14.3 y 5.x anterior a 5.4.1, un desbordamiento de lectura de búfer en la deserialización de Marshal (runtime/intern.c) permi... • https://github.com/ocaml/security-advisories/blob/generated-osv/2026/OSEC-2026-01.json • CWE-126: Buffer Over-read •

06 Apr 2018 — The caml_ba_deserialize function in byterun/bigarray.c in the standard library in OCaml 4.06.0 has an integer overflow which, in situations where marshalled data is accepted from an untrusted source, allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted object. La función caml_ba_deserialize en byterun/bigarray.c en la biblioteca estándar en OCaml 4.06.0 tiene un desbordamiento de enteros que, en situaciones en las que los datos serializado... • https://caml.inria.fr/mantis/view.php?id=7765 • CWE-190: Integer Overflow or Wraparound •
