High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue arises from the Linux kernel's handling of huge page sizes, where the
hugetlb no page() function calls folio zero user() with a fault address that may not be aligned with the huge page size. This can lead to folio zero user() calling clear gigantic page() with an unaligned address, which requires an address aligned with the huge page size. As a result, this can cause memory corruption or information leaks. The function clear gigantic page() has been updated to use a more obvious naming convention, 'addr hint' instead of 'addr', to reflect its purpose.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
