CVE-2026-64302

A flaw was found in the Linux kernel. A local user could exploit an issue in the pagetablefree 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 Denia...
