简介
远程 Red Hat 主机缺少一个或多个内核安全更新。描述
远程 Redhat Enterprise Linux 9 主机上安装的多个程序包受到 RHSA-2023:7749 公告中提及的多个漏洞影响。- 内核：smb2_is_status_io_timeout() 中存在释放后使用漏洞 (CVE-2023-1192)
- kernel：smb 客户端组件中的释放后使用漏洞 (CVE-2023-5345)
- hw amd：返回地址预测器的漏洞造成信息泄露 (CVE-2023-20569)
- kernel：IGB 驱动程序的缓冲区大小不足，无法用于大于 MTU 的帧 (CVE-2023-45871)
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
根据 RHSA-2023:7749 中的指南更新 RHEL 内核程序包。另见
