CVE-2026-28364 - OCaml Marshal Deserialization Buffer Over-Read Remote Code Execution

CVE ID : CVE-2026-28364 Published : Feb. 27, 2026, 3:54 a.m. | 23 minutes ago Description : 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.
