Summary
A flaw was found in the XFS filesystem within the Linux kernel. The `xfs_rtginode_ensure()` function incorrectly handles errors returned by `xfs_rtginode_load()`, treating I/O, allocation, or corruption errors as successful operations.
This oversight can result in the realtime group inode remaining unset, causing the `growfs` utility to proceed with an incomplete or corrupted inode. The primary consequence is potential data corruption or system instability during filesystem operations.
Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-253.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
