CVE-2022-41973 is a high-severity flaw (CVSS 7.8) affecting multipath-tools, fedora, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

multipath-tools 0.7.7 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited in conjunction with CVE-2022-41974. Local users able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which could lead to controlled file writes outside of the /dev/shm directory. This could be used indirectly for local privilege escalation to root.

opensvc multipath-tools UPGRADE

Affected: >= 0.7.7 and < 0.9.2

Fixed in: 0.9.2

Safe to downgrade to: a release before 0.7.7

1. Check installed version

apt-cache policy multipath-tools || rpm -q multipath-tools || multipath-tools --version

2. UPGRADE to 0.9.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade multipath-tools

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade multipath-tools

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 0.7.7 (Debian / Ubuntu)

apt-cache madison multipath-tools sudo apt install multipath-tools=<VERSION_BEFORE_0.7.7> sudo apt-mark hold multipath-tools

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

dnf --showduplicates list multipath-tools sudo dnf downgrade multipath-tools-<VERSION_BEFORE_0.7.7> sudo dnf versionlock add multipath-tools

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.
