kernel: mm: thp: deny THP for files on anonymous inodes

A flaw was found in the Linux kernel's Transparent Huge Pages THP mechanism. This vulnerability occurs because the filethpenabled function incorrectly allows THP for files on anonymous inodes, which are not designed for this feature. An attacker could potentially exploit this by manipulating...

Linux kernel 安全漏洞
