Privileged service interruption via divide by zero
Published Feb 17, 2021 · Updated Aug 4, 2024
Divide by zero in Intel Graphics Drivers before 26.20.100.8141 allows privileged local users to interrupt service. Intel identifies the arithmetic error but does not disclose the specific driver routine, divisor source, or input path that reaches the zero divisor. Exploitation requires privileged local access and affects availability only; the published record reports no data disclosure or modification.
