Linux Kernel Ext4 Filesystem Vulnerability Affecting Inode Management

CVE-2023-53270

What is CVE-2023-53270?

A vulnerability in the Linux kernel ext4 filesystem allows for a discrepancy where the i_disksize may exceed the i_size during partially written operations. This occurs due to improper handling of write operations, ultimately resulting in a warning condition. If not addressed, this issue may lead to undefined behavior during direct I/O operations, potentially complicating file integrity and system stability.
