NVIDIA NVFlash, NVUFlash Tool prior to v5.588.0 and GPUModeSwitch Tool prior to 2019-11, NVIDIA kernel mode driver (nvflash.sys, nvflsh32.sys, and nvflsh64.sys) contains a vulnerability in which authenticated users with administrative privileges can gain access to device memory and registers of other devices not managed by NVIDIA, which may lead to escalation of privileges, information disclosure, or denial of service.
CVE-2019-5688
This medium-severity CVE scores 6.7 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 71% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
