Overview

CVE-2024-51729 is a high-severity vulnerability. It was published on January 11, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

mm: use aligned address in copy_user_gigantic_page()

In current kernel, hugetlb_wp() calls copy_user_large_folio() with the

fault address. Where the fault address may be not aligned with the huge

page size. Then, copy_user_large_folio() may call

copy_user_gigantic_page() with the address, while

copy_user_gigantic_page() requires the address to be huge page size

aligned. So, this may cause memory corruption or information leak,

addtional, use more obvious naming 'addr_hint' instead of 'addr' for

copy_user_gigantic_page().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
