NVIDIA Triton (Python backend shared memory): Out-of-bounds write in the Python backend

CVE-2025-23319AI/ML frameworks & servingcurated

Impact

Out-of-bounds write in the Python backend

Who can reach it

Unauthenticated network

What to do

Patch; the Python backend's shared-memory region is the pivot in the Wiz chain

Fleet impact

How widespread

Very common - Triton is the default multi-model serving layer inside NIM and in many neocloud managed-inference products

Cost to remediate

daemon-restart (upgrade to 25.07, restart the serving process) - no host reboot, but it is a customer-visible endpoint outage

Why it hits the whole fleet

Unauthenticated remote chain: an oversized request leaks the internal shared-memory key, then an OOB write in the Python backend yields full RCE as the Triton process - i.e. theft of every model and every inference request on that server
