Title
accel/ivpu: Add buffer overflow check in MS get_info_ioctl
Summary
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.
Severity
CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
