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