CVE-2022-49352

A flaw was found in the Linux kernel's ext4 filesystem, which can lead to inconsistencies between an inode's in-memory size (i_size) and its on-disk size (i_disksize). This issue occurs when a file's size is increased, but the operation fails to mark the inode as dirty due to memory allocation errors (e.g., -ENOMEM). Consequently, i_disksize is updated while i_size remains unchanged, triggering warnings during direct I/O write operations, which can cause filesystem instability.
