An issue was discovered in ACRN before 2.5. dmar_free_irte in hypervisor/arch/x86/vtd.c allows an irte_alloc_bitmap buffer overflow.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
