CVE-2014-0038 本地 root 利用 漏洞: X86X32 的 recvmmsg 系统调用未正确清理从用户空间传递的超时指针。 利用原语: 将内核地址的指针作为超时参数传递给 recvmmsg，如果知道该地址的原始字节，就可以用已知数据覆盖它。如果最低有效字节是 0xff，等待 255 秒后它就会变成 0x00。 限制: 传递地址的第一个长整型（ tvsec ）必须为正，第二个长整型（ tvnsec ）必须小于 1000000000。 概述: 目标定位 ptmxfops 结构体中的 release...

Kernel: net: leakage of uninitialized memory to user-space via recv syscalls

The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have been initialized, which allows local users to obtain sensitive information from kernel stack memory via a 1 recvfrom, 2 recvmmsg, or 3 recvmsg system call, related to net/ipv4/ping.c,...
