virtio-balloon:修复 unrealize (CVE-2026-66899) 上的自由页 BH 拆卸

hw/net/virtio-net:缓存 RSC 段 (CVE-2026-66900) 时剥离尾部填充

hw/display/vga:修复图形表面切换 (CVE-2026-77913) 之后的文本模式 OOB 写入

在 QEMU 中发现一个缺陷。hw/i386/vapic.c 中的 VAPIC 设置超级调用未验证可写入的 RAM 别名是否保留在选项 ROM 窗口中。/KVM 计算机上的 Q35特权客户机用户可将此别名放置在锁定的 SMRAM 上,从而绕过芯片组D_LCK保护并将代码注入系统管理模式内存。(CVE-2026-81627)

io/channel-socket:不将零长度写入视为错误 (CVE-2026-84788)

在 QEMU 的 9pfs 子系统中发现一个释放后使用漏洞。处理并发 Tlcreate 和 Twalk 请求时,主线程和工作线程之间的争用条件允许恶意客户机用户构建包含过时堆数据的 fid 路径,从而绕过目录遍历限制并转义共享目录边界。这可导致以 QEMU 进程用户的身份读取/写入任意主机文件,以及执行代码(VM 转义)。(CVE-2026-93834)

Tenable 已直接从测试产品的安全公告中提取上述描述块。

请注意,Nessus 尚未测试这些问题,而是只依据应用程序自我报告的版本号进行判断。

解决方案

运行“dnf update qemu --releasever 2023.12.20261026”或“dnf update --advisory ALAS2023-2026-3241 --releasever 2023.12.20261026”以更新系统。
