CVE-2026-37540 Details
Description
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.
A vulnerability allowing integer overflow has been identified in the OpenAMP ELF loader version 2025.10.0. This issue arises during the parsing of firmware images, where the loader multiplies two 16-bit values from the ELF header without proper overflow checks. On 32-bit embedded systems such as STM32MP1, Zynq, and i.MX, this can lead to the creation of a small value from a large one, causing memory corruption by overwriting host memory with crafted ELF images.
