CVE-2026-53203
Description
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.
