Ubuntu 16.04 LTS / 18.04 LTS:Linux 内核漏洞 (USN-5164-1)

medium Nessus 插件 ID 155747

简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 16.04 LTS/18.04 LTS 主机上安装的程序包受到 USN-5164-1 公告中提及的多个漏洞的影响。

- Linux 内核 5.13.4 及之前的所有版本中,drivers/net/usb/hso.c 中的 hso_free_net_device 在调用 unregister_netdev 时未检查 NETREG_REGISTERED 状态,从而导致释放后使用和双重释放。
(CVE-2021-37159)

- 在 Linux 内核的 drivers/crypto/ccp/ccp-ops.c 的 ccp_run_aes_gcm_cmd() 函数中发现一个内存泄漏缺陷,攻击者可利用此缺陷造成拒绝服务(内存消耗)。
此缺陷与较早版本的 CVE-2019-18808 类似。(CVE-2021-3744)

请注意,Nessus 尚未测试此问题,而是只依靠应用程序自我报告的版本号来判断。

解决方案

更新受影响的程序包。
