CVE-2022-23648
Description
An information leak was discovered in containerd. This issue could allow a remote attacker access to read-only copies of arbitrary files and directories on the host, which can be exploited with a specially-crafted image configuration.
Statement
For several Red Hat products containerd is shipped but cri-o (which is not affected by this flaw) is used by default. For this reason, the impact has been downgraded to Low.
Common Vulnerability Scoring System (CVSS) Score Details
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).
The following CVSS metrics and score provided are preliminary and subject to review.
