Hi,
The following vulnerability was published for ocaml.
CVE-2026-28364[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
