CVE-2023-28907 (GCVE-0-2023-28907)

Vulnerability from cvelistv5 – Published: 2025-06-28 15:36 – Updated: 2025-06-30 19:20
VLAI?
Title
A lack of access restrictions on internal memory regions
Summary
There is no memory isolation between CPU cores of the MIB3 infotainment. This fact allows an attacker with access to the main operating system to compromise the CPU core responsible for CAN message processing. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

Title
Integer Overflow in Non-Fragmented Data Reception
Summary
A specific flaw exists within the Bluetooth stack of the MIB3 infotainment. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow when receiving non-fragmented HCI packets on a channel. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

CVE-2023-28909 (GCVE-0-2023-28909)

Vulnerability from cvelistv5 – Published: 2025-06-28 15:35 – Updated: 2025-06-30 19:21

Title
Integer Overflow Leading to MTU Bypass
Summary
A specific flaw exists within the Bluetooth stack of the MIB3 unit. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow when receiving fragmented HCI packets on a channel. An attacker can leverage this vulnerability to bypass the MTU check on a channel with enabled fragmentation. Consequently, this can lead to a buffer overflow in upper layer profiles, which can be used to obtain remote code execution. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

Title
Arbitrary Channel Disconnection Resulting in Denial of Service
Summary
A specific flaw exists within the Bluetooth stack of the MIB3 infotainment. The issue results from the lack of proper validation of user-supplied data, which can result in an arbitrary channel disconnection. An attacker can leverage this vulnerability to cause a denial-of-service attack for every connected client of the infotainment device. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

Title
A lack of access control in custom IPC mechanism
Summary
The MIB3 infotainment unit used in Skoda and Volkswagen vehicles does not incorporate any privilege separation for the proprietary inter-process communication mechanism, leaving attackers with presence in the system an ability to undermine access control restrictions implemented at the operating system level. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

Title
A lack of access restrictions on internal memory regions
Summary
There is no memory isolation between CPU cores of the MIB3 infotainment. This fact allows an attacker with access to the main operating system to compromise the CPU core responsible for CAN message processing. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

Title
Integer Overflow in Non-Fragmented Data Reception
Summary
A specific flaw exists within the Bluetooth stack of the MIB3 infotainment. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow when receiving non-fragmented HCI packets on a channel. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

CVE-2023-28909 (GCVE-0-2023-28909)

Title
Integer Overflow Leading to MTU Bypass
Summary
A specific flaw exists within the Bluetooth stack of the MIB3 unit. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow when receiving fragmented HCI packets on a channel. An attacker can leverage this vulnerability to bypass the MTU check on a channel with enabled fragmentation. Consequently, this can lead to a buffer overflow in upper layer profiles, which can be used to obtain remote code execution. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.

Title
Arbitrary Channel Disconnection Resulting in Denial of Service
Summary
A specific flaw exists within the Bluetooth stack of the MIB3 infotainment. The issue results from the lack of proper validation of user-supplied data, which can result in an arbitrary channel disconnection. An attacker can leverage this vulnerability to cause a denial-of-service attack for every connected client of the infotainment device. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.
