CVE-2020-27024

Status: ModifiedHigh (7.5)—

In smp_br_state_machine_event of smp_br_main.cc, there is a possible out of bounds read due to a missing bounds check. This could lead to remote information disclosure triggered by a malformed Bluetooth packet, with no additional execution privileges needed. User interaction is not needed for exploitation. Bounds Sanitizer mitigates this in the default configuration.Product: AndroidVersions: Android-11Android ID: A-162327732

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).
