Описание
Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest integrity.
A flaw was found in hw. Insufficient checks of the RMP on host buffer access in the Input-Output Memory Management Unit (IOMMU) allows an attacker with privileges and a compromised hypervisor to trigger an out-of-bounds condition without RMP checks. This issue results in the potential loss of guest integrity.
Отчет
Red Hat has stack protection mechanisms in place, such as FORTIFY_SOURCE, Position Independent Executables or Stack Smashing Protection.
