**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 `gup pud range()` function for dax. The issue occurs when `pud huge()` returns true on x86, but dax does not depend on hugetlb. This fix addresses a kernel panic caused by a general protection fault, probably for a non-canonical address. The call trace includes functions such as `get user pages fast()`, `iov iter get pages()`, and `bio iov iter get pages()`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
