Security readout for executives and security teams
Plain-English summary
This is a local privilege escalation in openSUSE Tumbleweed's keylime package. A flaw in the package's %post scriptlet could let someone already operating as the keylime user gain root privileges. It is not described as remotely exploitable.
Executive priority
Prioritize remediation on openSUSE Tumbleweed hosts where keylime is installed, especially systems with broader local user access. This is not a remote internet-facing bug, but root escalation can materially worsen an existing foothold.
Technical view
CVE-2022-31250 is a CWE-59 symlink-following issue in keylime on openSUSE Tumbleweed before 6.4.2-1.1. The CVSS 3.1 vector is local, low complexity, low privileges, no user interaction, with high confidentiality and integrity impact.
Likely exposure
Exposure appears limited to openSUSE Tumbleweed systems with vulnerable keylime versions prior to 6.4.2-1.1. The attacker needs local access and privileges as the keylime user.
Exploitation context
The source bundle does not confirm active exploitation, and the CVE is not listed as KEV. The risk is serious where local account compromise or service abuse could place an attacker in the keylime user context.
Researcher notes
Evidence supports a local symlink-following flaw in keylime packaging behavior, specifically the %post scriptlet. Public details in the bundle are sparse; avoid assuming exploit availability or affected distributions beyond openSUSE Tumbleweed.
Mitigation direction
- Upgrade keylime on openSUSE Tumbleweed to version 6.4.2-1.1 or later.
- Check SUSE guidance for any additional package-specific remediation.
- Restrict access paths that can execute code as the keylime user.
- Review local account and service permissions around keylime deployments.
Validation and detection
- Inventory openSUSE Tumbleweed hosts running keylime.
- Confirm installed keylime versions are 6.4.2-1.1 or later.
- Review package update history for vulnerable installations.
- Check whether any services or users can operate as the keylime account.
- Monitor for suspicious privilege changes from the keylime user to root.

Improper Link Resolution Before File Access ('Link Following') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
