Routine

HIGH 7.5UPGRADE

CVE-2022-25837 is a high-severity flaw (CVSS 7.5) affecting bluetooth core specification. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Bluetooth® Pairing in Bluetooth Core Specification v1.0B through v5.3 may permit an unauthenticated MITM to acquire credentials with two pairing devices via adjacent access when at least one device supports BR/EDR Secure Connections pairing and the other BR/EDR Legacy PIN code pairing if the MITM negotiates BR/EDR Secure Simple Pairing in Secure Connections mode using the Passkey association model with the pairing Initiator and BR/EDR Legacy PIN

Why this priority

High severity

A fixed release or distro patch exists.

bluetooth bluetooth core specification UPGRADE

Affected: >= 1.1b and <= 5.3

Fixed in: newer than 5.3

Safe to downgrade to: a release before 1.1b

1. Check installed version

apt-cache policy bluetooth-core-specification || rpm -q bluetooth-core-specification || bluetooth-core-specification --version

2. UPGRADE to newer than 5.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade bluetooth-core-specification

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade bluetooth-core-specification

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.1b (Debian / Ubuntu)

apt-cache madison bluetooth-core-specification sudo apt install bluetooth-core-specification=<VERSION_BEFORE_1.1b> sudo apt-mark hold bluetooth-core-specification

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list bluetooth-core-specification sudo dnf downgrade bluetooth-core-specification-<VERSION_BEFORE_1.1b> sudo dnf versionlock add bluetooth-core-specification

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
