CVE-2024-49859

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58

Description: A potential race issue has been identified in certain f2fs ioctl interfaces, such as f2fs ioc set pin file(), f2fs move file range(), and f2fs defragment range(), due to a missing check for atomic write status. This issue may cause problems, but details about the estimated number of potentially affected devices or real-world incidents are not provided.

Recommendations: For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider restricting the use of the vulnerable f2fs ioctl interfaces until a patch is available.
