CVE-2022-50448 Details
Description
In the Linux kernel, the following vulnerability has been resolved: mm/uffd: fix warning without PTE_MARKER_UFFD_WP compiled in When PTE_MARKER_UFFD_WP not configured, it's still possible to reach pte marker code and trigger an warning. Add a few CONFIG_PTE_MARKER_UFFD_WP ifdefs to make sure the code won't be reached when not compiled in.
A vulnerability in the Linux kernel related to the Userfaultfd write-protection feature has been addressed. When the PTE_MARKER_UFFD_WP option is not enabled, the kernel can still encounter code related to this feature, leading to a warning. The issue has been fixed by adding conditional compilation directives to prevent the code from being executed when PTE_MARKER_UFFD_WP is not available.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation or through the package management system of the respective Linux distribution.
