CVE-2020-0471

Status: ModifiedCritical (9.8)—💥 PoC

In reassemble_and_dispatch of packet_fragmenter.cc, there is a possible way to inject packets into an encrypted Bluetooth connection due to improper input validation. This could lead to remote escalation of privilege between two Bluetooth devices by a proximal attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android; Versions: Android-8.0, Android-8.1, Android-9, Android-10, Android-11; Android ID: A-169327567.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
