Linux Kernel nilfs2 Vulnerability in Read-Only Mode

CVE-2023-53337

What is CVE-2023-53337?

The nilfs2 subsystem of the Linux kernel experiences issues when switching to read-only mode after detecting metadata corruption. This can lead to erroneous warnings and potential data integrity risks. Specifically, the function mark_buffer_dirty() issues a warning when invoked inappropriately, after the file system has already transitioned to a read-only state. The fix ensures that write operations abort appropriately during this condition, enhancing system stability and preventing unnecessary log write retries.
