1) Cryptographic issues

EUVDB-ID: #VU20290

Risk: Low

CVSSv3.1: 3.5 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-9506

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists due to a weakness in Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol core specification that allows an attacker with close proximity to the affected system to perform a man-in-the-middle attack on an encrypted Bluetooth connection.

Successful exploitation of the vulnerability may allow an attacker to gain access to sensitive information or perform unauthorized actions.

Mitigation

2) Information disclosure

EUVDB-ID: #VU19946

Risk: Low

CVSSv3.1: 8.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2019-1125

CWE-ID: CWE-200 - Information exposure

Exploit availability: Yes

Description

The vulnerability allows a local user to gain access to potentially sensitive information and elevate privileges on the system.

The vulnerability exists when certain central processing units (CPU) speculatively access memory. A local user can gain unauthorized access to sensitive information and elevate privileges on the system.

This issue is a variant of the Spectre Variant 1 speculative execution side channel vulnerability that leverages SWAPGS instructions to bypass KPTI/KVA mitigations.
