What is CVE-2026-23416?

A vulnerability in the Linux Kernel's memory management system was found, specifically affecting how the end of Virtual Memory Areas (VMAs) is updated. Previously, the end of a VMA was stored in a variable, which led to potential stale values when merging VMAs. This could result in incorrect memory references during operations. The issue has been resolved by ensuring that the end of a VMA is updated unconditionally, which simplifies the logic and enhances the integrity of memory management across VMAs.
