Linux Distros 未修补的漏洞：CVE-2023-52701
high Nessus 插件 ID 225927
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- net使用反弹缓冲区进行复制 skb->mark syzbot 发现 CONFIG_HARDENED_USERCOPY=y 时arm64 版本在 sock_recv_mark() 中会崩溃 x86 和 powerpc 未检测此问题因为它们定义了 user_access_begin。此问题将在不同的修补程序中处理因为缺少 check_object_size()。
只有来自 skb->cb[] 的数据可以直接复制到用户空间或从用户空间复制如 commit 79a8a642bf05 (net将 skbuff_head_cache cb 字段列入白名单) 中所述syzbot 报告为: usercopy从 SLUB 对象“skbuff_head_cache”中检测到内核内存泄露尝试偏移 168大小 4 ------------[在此处切换]------------ mm/usercopy.c:102 的内核缺陷内部错误Oops - BUG: 00000000f2000800 [#1] CPU:0 PID: 4410 Comm: syz-executor533 Not tainted 6.2.0-rc7-syzkaller-17907-g2d3827b3f393 #0 硬件名称: Google Google Compute 中链接的 PREEMPT SMP 模块Engine/Google 计算引擎BIOS Google 01/21/2023 pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc
