**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a memory leak in the `hugetlb mcopy atomic pte()` function. When the code bails out using "goto out release unlock;" in certain cases, it detects that `new pagecache page` is false and calls `restore reserve on error()`, which deletes the reservation. This leads to a 100% reproducible leak when `remove inode hugepages()` is called, causing `h->resv hugepages` to increment. The problem can be resolved by treating the `is continue` case similar to adding a page into the pagecache and setting `new pagecache page` to true. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
