This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub&#39;s heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved.</p> <p><strong>Affected:</strong> grub, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 7</p> <p>An out-of-bounds write flaw was found in grub2&#39;s NTFS filesystem driver.
