Azure Linux 3.0 安全更新内核 (CVE-2024-57890)

medium Nessus 插件 ID 233138

语言：

简介

远程 Azure Linux 主机缺少一个或多个安全更新。

描述

远程 Azure Linux 3.0 主机上安装的内核版本低于 测试的版本。因此，该程序受到 CVE-2024-57890 公告中提及的一个漏洞影响。

 - 已修复 Linux 内核中的下列漏洞：RDMA/uverbs: Prevent integer overflow issue In the expression cmd.wqe_size * cmd.wr_count, both variables are u32 values that come from the user so the multiplication can lead to integer wrapping. Then we pass the result to uverbs_request_next_ptr() which also could potentially wrap. The cmd.sge_count * sizeof(struct ib_uverbs_sge) multiplication can also overflow on 32bit systems although it's fine on 64bit systems.
 This patch does two things. First, I've re-arranged the condition in uverbs_request_next_ptr() so that the use controlled variable len is on one side of the comparison by itself without any math. Then I've modified all the callers to use size_mul() for the multiplications. (CVE-2024-57890)
