説明
An privilege chaining vulnerability was discovered in the util-linux package. A local, authenticated attacker could use mesg or wall to takeover another user's account.

CVSS (Common Vulnerability Scoring System) のスコアの詳細
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
