Description
In the Linux kernel, the following vulnerability has been resolved:
vduse: fix memory corruption in vduse_dev_ioctl()
The "config.offset" comes from the user. There needs to a check to
prevent it being out of bounds. The "config.offset" and
"dev->config_size" variables are both type u32. So if the offset if
out of bounds then the "dev->config_size - config.offset" subtraction
results in a very high u32 value. The out of bounds offset can result
in memory corruption.
