Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
