Deeper analysis
CVE-2022-28653 is a vulnerability that allows users to consume unlimited disk space in the /var/crash directory. The issue carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high-impact availability disruption with no confidentiality or integrity effects. No specific software or component is detailed in the available information, and it maps to NVD-CWE-noinfo.
Remote attackers require no privileges or user interaction to exploit this over the network with low complexity. Successful exploitation enables denial-of-service by filling the /var/crash directory with unlimited data, potentially exhausting disk resources and disrupting system operations.
