CVE-2022-49655

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists in the Linux kernel's fscache, specifically when handling NFS files. If an NFS file is opened for writing, closed, and then modified locally, the cache contents may not be updated, potentially leading to file corruption. This issue arises when the cookie is in the LOOKING UP state and the request to invalidate doesn't get recorded. The fix involves setting a flag in fscache invalidate() to indicate the need for invalidation when the cookie is in the LOOKING UP state.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
