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.

Exploit prediction (EPSS)

0.79% probability of exploitation in the next 30 days, higher than 56% of all scored CVEs.
