CVE-2025-22113 is a race condition in the Linux kernel ext4 filesystem's error-handling and unmount paths. During JBD2 journal destruction, an inode error can cause ext4_handle_error to schedule deferred superblock-update work after previously pending work has been flushed. The update_super_work function can then attempt to start a journal transaction after JBD2_UNMOUNT has been set, triggering a BUG_ON assertion. The fix tracks journal destruction with a mount-state flag and uses an unjournaled superblock commit when destruction is underway.

A Linux kernel ext4 error-handling flaw involving superblock journaling updates while the journal is being destroyed, affecting Rocky Linux 9 kernel packages in CIQ advisory crlsa-2025_11861.
A Linux kernel ext4/JBD2 availability flaw during filesystem unmount and error handling. A deferred superblock update can attempt to use a journal marked for destruction, causing a kernel BUG_ON and potential local denial of service.
An ext4 vulnerability involving journaling a superblock update on an error while the journal is being destroyed. Red Hat addresses it in Important-rated advisory RHSA-2025:12662. The advisory does not specify the exploitation impact; the kernel update requires a reboot.
A Linux kernel ext4 filesystem flaw involving a superblock journaling update during an error condition while the journal is being destroyed.
