Kerentanan Heap-based Buffer Overflow pada gnu grub2, redhat enterprise linux. Skor CVSS 3.1 7.8 (High) menurut NVD.
An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub'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.
