Kerentanan Improper Restriction of Operations within the Bounds of a Memory Buffer pada freebsd. Skor CVSS 3.1 7.8 (High) menurut NVD.

Deskripsi (NVD)

grub2-bhyve, as used in FreeBSD bhyve before revision 525916 2020-02-12, does not validate the address provided as part of a memrw command (read_* or write_*) by a guest through a grub2.cfg file. This allows an untrusted guest to perform arbitrary read or write operations in the context of the grub-bhyve process, resulting in code execution as root on the host OS.
