Memory Management Flaw in Linux Kernel Affects System Stability

CVE-2026-98373

What is CVE-2026-98373?

A vulnerability in the Linux kernel's memory management system has been identified, where the handling of hugetlb page tables during memory remapping was flawed. Specifically, the advancement of destination addresses was incorrectly calculated, which could lead to discrepancies and a potential kernel panic, particularly in x86-64 architectures. This issue has been resolved by ensuring that the destination address advances correspondingly only to the source advance distance, thus preserving system stability during memory operations.
