CVE-2024-47689

CVSS v3.1

5.3

Medium

VectorAV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.58
Description A vulnerability in the Linux kernel has been resolved, specifically in the f2fs filesystem. The issue arises from the f2fs setting the SB RDONLY flag in an internal function rather than through the remount procedure, leading to a race condition. This bug can cause issues when handling critical errors in the filesystem, particularly when mounted with the errors=remount-ro option. The vulnerability is related to the f2fs handle critical error function and the SB RDONLY flag.
Recommendations To resolve the issue, update the Linux kernel to version 6.6.58 or later. As a temporary workaround, consider disabling the f2fs handle critical error function until a patch is available. Restrict access to the vulnerable f2fs filesystem to minimize the risk of exploitation. Avoid using the SB RDONLY flag in the affected filesystem until the issue is resolved.
