An issue was discovered on Samsung mobile devices with Q(10.0) and R(11.0) (Qualcomm SM8250 chipsets) software. They allows attackers to cause a denial of service (unlock failure) by triggering a power-shortage incident that causes a false-positive attack detection. The Samsung ID is SVE-2020-19678 (December 2020).

Abbott Laboratories pacemakers manufactured prior to Aug 28, 2017 do not restrict or limit the number of correctly formatted "RF wake-up" commands that can be received, which may allow a nearby attacker to repeatedly send commands to reduce pacemaker battery life. CVSS v3 base score: 5.3, CVSS vector string: AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H. Abbott has developed a firmware update to help mitigate the identified vulnerabilities.
