**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability in the Linux kernel has been resolved, related to the `cachestat()` system call. The issue arose when `cachestat()` was added as a more convenient and performant version of `mincore()`, but it missed a fix for checking writability or ownership. This fix, initially applied to `mincore()` in a previous commit, has now been added to `cachestat()` with modifications for the file context. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
