摘要:
qemu security update
安全等级: Low
公告ID: KylinSec-SA-2024-4131
发布日期: 2024年10月18日
关联CVE: CVE-2024-8612
QEMU是一款使用动态转换技术来实现高速模拟的快速处理器模拟器。
安全修复：
在QEMU的virtio-scsi、virtio-blk和virtio-crypto设备中发现了一个漏洞。在virtio_scsi_complete_req、virtio_blk_req_complete和virtio_crypto_req_complete中设置的virtqueue_push的大小可能会大于已发送给客户机的数据的实际大小。当virtqueue_push()最终调用dma_memory_unmap来取消映射in_iov时，它可能会调用address_space_write函数来将数据写回。在bounce.buffer中可能存在一些未初始化的数据，从而导致信息泄露。(CVE-2024-8612)
