Samsung Kernel /dev/vipx Pointer Leak

Samsung Kernel /dev/vipx Pointer Leak
Posted Feb 27, 2020
Authored by Google Security Research, bazad

The function __vipx_ioctl_put_container() in the Samsung kernel calls copy_to_user() on a vs4l_container_list structure that contains a kernel pointer, exposing that kernel pointer to userspace just before it gets passed to kfree().
