CVE-2025-23269

Local information disclosure via shared predictor state

Published Jul 17, 2025 · Updated Jul 17, 2025

Information disclosure in the NVIDIA Jetson Linux kernel before 35.6.2 or 36.4.4 allows local users to read sensitive data. Shared microarchitectural predictor state lets attacker-controlled code influence transient kernel execution and infer protected data across a hardware boundary. Exploitation requires local low-privileged execution and high-complexity predictor manipulation; the reported impact is limited to confidentiality.
