VAR-201706-0816

Vulnerability from variot - Updated: 2023-12-18 13:08

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). Remote attackers can exploit this issue to bypass certain security restrictions and perform unauthorized actions. ARM Trusted Firmware through 1.3 are vulnerable; other versions may also be affected

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
