Overview

CVE-2023-53081 is a high-severity vulnerability. It was published on May 2, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: fix data corruption after failed write

When buffered write fails to copy data into underlying page cache page,

ocfs2_write_end_nolock() just zeroes out and dirties the page. This can

leave dirty page beyond EOF and if page writeback tries to write this page

before write succeeds and expands i_size, page gets into inconsistent

state where page dirty bit is clear but buffer dirty bits stay set

resulting in page data never getting written and so data copied to the

page is lost. Fix the problem by invalidating page beyond EOF after

failed write.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
