Description

This security bulletin contains information about 5 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2021-31610)

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

CVSSv4: 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


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.


2) Heap-based buffer overflow (CVE-ID: CVE-2021-34149)

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

CVSSv4: 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


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.


3) Heap-based buffer overflow (CVE-ID: CVE-2021-34146)

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

CVSSv4: 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

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.


4) Heap-based buffer overflow (CVE-ID: CVE-2021-34143)

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

CVSSv4: 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


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.


5) Input validation error (CVE-ID: CVE-2021-34144)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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


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

The vulnerability exists due to the Bluetooth Classic implementation does not properly handle the reception of truncated LMP_SCO_Link_Request packets while no other BT connections are active. A remote attacker in radio range can send a specially crafted LMP packet and perform a denial of service (DoS) attack.
