Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU56321
Risk: Low
CVSSv4.0: 4.9 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-31610
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe 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.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
