CVE-2020-14385 (GCVE-0-2020-14385)

Vulnerability from cvelistv5 – Published: 2020-09-15 21:14 – Updated: 2024-08-04 12:46
VLAI
Summary
A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability.
