This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub\u0026apos;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.(CVE-2023-4692)\r\n\r\nAn out-of-bounds read flaw was found on grub2\u0026apos;s NTFS filesystem driver.
