NCR SelfServ ATMs running APTRA XFS 05.01.00 or earlier do not authenticate or protect the integrity of USB HID communications between the currency dispenser and the host computer, permitting an attacker with physical access to internal ATM components the ability to inject a malicious payload and execute arbitrary code with SYSTEM privileges on the host computer by causing a buffer overflow on the host.
CVE-2020-5953 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Ape1808, Ruggedcom Ape1808 Firmware and 30 more 2025-11-04 7.5 High
A vulnerability exists in System Management Interrupt (SWSMI) handler of InsydeH2O UEFI Firmware code located in SWSMI handler that dereferences gRT (EFI_RUNTIME_SERVICES) pointer to call a GetVariable service, which is located outside of SMRAM. This can result in code execution in SMM (escalating privilege from ring 0 to ring -2).
CVE-2020-27339 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Apr1808, Ruggedcom Apr1808 Firmware and 30 more 2025-11-04 6.7 Medium
In the kernel in Insyde InsydeH2O 5.x, certain SMM drivers did not correctly validate the CommBuffer and CommBufferSize parameters, allowing callers to corrupt either the firmware or the OS memory. The fixed versions for this issue in the AhciBusDxe, IdeBusDxe, NvmExpressDxe, SdHostDriverDxe, and SdMmcDeviceDxe drivers are 05.16.25, 05.26.25, 05.35.25, 05.43.25, and 05.51.25 (for Kernel 5.1 through 5.5).
CVE-2020-26560 1 Bluetooth 1 Mesh Profile 2025-11-04 8.1 High
Bluetooth Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device, reflecting the authentication evidence from a Provisioner, to complete authentication without possessing the AuthValue, and potentially acquire a NetKey and AppKey.
CVE-2020-26559 1 Bluetooth 1 Mesh Profile 2025-11-04 8.8 High
Bluetooth Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (participating in the provisioning protocol) to identify the AuthValue used given the Provisioner’s public key, and the confirmation number and nonce provided by the provisioning device. This could permit a device without the AuthValue to complete provisioning without brute-forcing the AuthValue.
CVE-2020-26558 6 Bluetooth, Debian, Fedoraproject and 3 more 35 Bluetooth Core Specification, Debian Linux, Fedora and 32 more 2025-11-04 4.2 Medium
Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.
CVE-2020-26557 1 Bluetooth 1 Mesh Profile 2025-11-04 7.5 High
Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (without possession of the AuthValue used in the provisioning protocol) to determine the AuthValue via a brute-force attack (unless the AuthValue is sufficiently random and changed each time).
CVE-2020-26555 4 Bluetooth, Fedoraproject, Intel and 1 more 33 Bluetooth Core Specification, Fedora, Ac 3165 and 30 more 2025-11-04 5.4 Medium
