CVE-2026-64302
Description
A flaw was found in the Linux kernel. A local user could exploit an issue in the pagetable_free() function, which incorrectly handles vmemmap pages. This improper memory management leads to a memory leak, where only a portion of the allocated memory is freed. Consequently, this can result in a Denial of Service (DoS) due to resource exhaustion.
