Description

This security bulletin contains information about 4 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2021-31609)

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 an oversized LMP packet greater than 17 bytes. A remote attacker in radio range can send a specially crafted LMP packet and perform a denial of service (DoS) attack.


2) Input validation error (CVE-ID: CVE-2021-31612)

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 an oversized LMP packet greater than 17 bytes. A remote attacker in radio range can send a specially crafted LMP packet and perform a denial of service (DoS) attack.


3) Input validation error (CVE-ID: CVE-2021-31613)

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 a truncated LMP packet during LMP auto rate procedure. A remote attacker in radio range can pass specially crafted input to the application and perform a denial of service (DoS) attack.


4) Input validation error (CVE-ID: CVE-2021-31611)

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 an out-of-order LMP Setup procedure (c.f., Figure 1) followed by a malformed LMP packet. A remote attacker in radio range can pass specially crafted input to the application and perform a denial of service (DoS) attack.
