CVE-2026-53342
Description
A flaw was found in the Linux kernel, specifically within the ARM64 architecture's memory management. This vulnerability occurs because the system fails to properly deallocate page tables that have been hot-removed, leading to memory leaks. This can result in incorrect memory usage statistics and, under certain debugging configurations, trigger system warnings indicating a bad page state. The issue stems from missing calls to the pagetable_dtor() function, which is responsible for cleaning up page table resources.
