Security Bulletin

This security bulletin contains information about 9 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU56321

Risk: Low

CVSSv3.1: 6 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2021-31610

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation on several chipsets does not properly handle the reception of continuous unsolicited LMP responses. A remote attacker in radio range can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service condition on the target system.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
