Naam: Improper Handling of Overlap Between Protected Memory Ranges

The product allows address regions to overlap, which can result in the bypassing of intended memory protection.

Detectiemethoden

Manual Analysis

Create a high privilege memory block of any arbitrary size. Attempt to create a lower privilege memory block with an overlap of the high privilege memory block. If the creation attempt works, fix the hardware. Repeat the test.
Effectiviteit : High

Notities kwetsbaarheidsmapping

Rechtvaardiging : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Opmerking : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Gerelateerde aanvalspatronen

CAPEC-ID Naam aanvalspatroon
CAPEC-456 Infected Memory
An adversary inserts malicious logic into memory enabling them to achieve a negative impact. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems that are still under development and part of the supply chain.

Notities

As of CWE 4.6, CWE-1260 and CWE-1316 are siblings under view 1000, but CWE-1260 might be a parent of CWE-1316. More analysis is warranted.
