GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2017-7563 (GCVE-0-2017-7563)

Vulnerability from cvelistv5 – Published: 2017-06-07 15:00 – Updated: 2024-08-05 16:04
VLAI
Summary
In ARM Trusted Firmware 1.3, RO memory is always executable at AArch64 Secure EL1, allowing attackers to bypass the MT_EXECUTE_NEVER protection mechanism. This issue occurs because of inconsistency in the number of execute-never bits (one bit versus two bits).
