CVE-2026-46080

A flaw was found in the Linux kernel's Oracle Cluster File System 2 (ocfs2) component. During direct I/O (DIO) write operations, specifically in the `ocfs2_dio_end_io_write` function, an issue with transaction splitting can lead to credit exhaustion in the Journaling Block Device 2 (JBD2) subsystem. This can be exploited by a local attacker to cause a denial of service (DoS) by preventing further journaling operations.
