CVE-2017-9607 (GCVE-0-2017-9607)

Vulnerability from cvelistv5 – Published: 2017-09-20 16:00 – Updated: 2024-08-05 17:11

Summary

The BL1 FWU SMC handling code in ARM Trusted Firmware before 1.4 might allow attackers to write arbitrary data to secure memory, bypass the bl1_plat_mem_check protection mechanism, cause a denial of service, or possibly have unspecified other impact via a crafted AArch32 image, which triggers an integer overflow.
