Doc Text:
A flaw was found in OpenAMP. An integer overflow vulnerability exists in the ELF loader's firmware image parsing, specifically within elf_loader.c. This flaw occurs when multiplying two attacker-controlled 16-bit values from the ELF header without proper overflow checking. On 32-bit embedded systems, large input values can cause the product to wrap around, potentially leading to arbitrary code execution, privilege escalation, or denial of service.

Description OSIDB Bzimport 2026-05-01 17:02:40 UTC 
OpenAMP v2025.10.0 ELF loader contains an integer overflow vulnerability in firmware image parsing. In elf_loader.c, it performs multiplication of two attacker-controlled 16-bit values from the ELF header without overflow checking. On 32-bit embedded systems (STM32MP1, Zynq, i.MX), large values can cause the product to wrap around to a small value.
