CVE-2025-33216

Service crash via buffer-size miscalculation

Published Mar 24, 2026 · Updated Mar 24, 2026

Incorrect buffer-size calculation in NVIDIA DOCA SNAP-4 Service Container allows guest OS users to crash the service via crafted configurations. The configuration interface derives an incorrect buffer size from attacker-controlled configuration data, and the resulting processing failure terminates the service. Exploitation requires access from a guest VM on a BlueField-3 system and interrupts storage service availability to the host; no data disclosure or modification is reported.
