Linux kernel 2.6.x snd_ctl_new()函数整数溢出漏洞

Linux Kernel是Linux操作系统所使用的内核。 Linux Kernel的sound/core/control.c文件中的sndctlnew函数未经执行边界检查便通过对用户所提供的大小执行算术操作来为sndkcontrol结构分配空间。如果用户提供了足够大的大小，就会出现溢出，导致分配过小的块，之后用户提供的值就会越界。 拥有通过SNDRVCTLIOCTLELEMADD和SNDRVCTLIOCTLELEMREPLACE ioctl打开/dev/snd/controlC设备（通常为audio组）的非特权用户可到达有漏洞的代码。成功利用这个漏洞的攻击者可以导致拒绝服务或获得权限提...
