Local data tampering via arbitrary write
Published Jul 14, 2026 · Updated Jul 14, 2026
Memory corruption in NVIDIA TensorRT-LLM 1.3.0rc16 and earlier allows local users to write data, interrupt service, or read data. NVIDIA identifies a write-what-where condition but has not disclosed the affected component, attacker-controlled value or destination, or operation that performs the write. Exploitation requires local access, no privileges or user interaction, and high-complexity conditions; the bounded impacts are data tampering, service interruption, and information disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.0 <=v1.3.0 rc16
