CVE-2026-10047: Bitdefender Napoca bare-metal hypervisor, грешка в

Описание

Оригинално описание

The Bitdefender Napoca bare-metal hypervisor contains an out-of-bounds write vulnerability in the real-mode hook handler, implemented in napoca/kernel/handler.c. The handler uses a guest-controlled SS:SP-derived offset as an index into the 1MB RealModeMemory buffer without bounds validation. With SS=0xFFFF and ESP=0xFFFF, the computed offset can reach 0x10FFEF, exceeding the RealModeMemory buffer by 65,519 bytes. The IRET frame push can therefore write past the end of the buffer into the hypervisor heap. The product is end-of-life and unsupported when assigned.
