Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-06-30 03:37

Details

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

7.1 (High)
