Overview

CVE-2024-50230 is a high-severity vulnerability. It was published on November 9, 2024 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. No authentication or special privileges are required for exploitation.

Technical description

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

nilfs2: fix kernel bug due to missing clearing of checked flag

Syzbot reported that in directory operations after nilfs2 detects

filesystem corruption and degrades to read-only,

__block_write_begin_int(), which is called to prepare block writes, may

fail the BUG_ON check for accesses exceeding the folio/page size,

triggering a kernel bug.

This was found to be because the "checked" flag of a page/folio was not

cleared when it was discarded by nilfs2's own routine, which causes the

sanity check of directory entries to be skipped when the directory

page/folio is reloaded. So, fix that.

This was necessary when the use of nilfs2's own page discard routine was

applied to more than just metadata files.

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.
