Description OSIDB Bzimport 2026-06-25 10:06:19 UTC
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.
