What it is

In the Linux kernel, the following vulnerability has been resolved:

accel/ivpu: Add buffer overflow check in MS get_info_ioctl

Add validation that the info size returned from the metric stream info

query is not exceeded when checked against the allocated buffer size.

If the firmware returns a size larger than the buffer, reject the

operation with -EOVERFLOW instead of proceeding with an incorrect

buffer copy.
