VAR-202207-0317

Vulnerability from variot - Updated: 2024-08-14 12:31

In Bluetooth, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06784351; Issue ID: ALPS06784351. MediaTek Inc. is the world's fourth largest fab semiconductor company, with a leading position in mobile terminals, smart home applications, wireless connectivity technologies and IoT products, with approximately 1.5 billion units a year End products with built-in MediaTek chips are available worldwide.

Several MediaTek chips have a buffer overflow vulnerability in Bluetooth that stems from a lack of bounds checking in Bluetooth. An attacker could exploit the vulnerability to escalate local privileges without requiring user interaction

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
