CVE-2026-47554 — Improper Verification of Cryptographic Signature in NVIDIA GeForce

NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where improper verification of cryptographic signatures may cause signature verification to be bypassed under memory pressure. A successful exploit of this vulnerability might lead to denial of service and data tampering.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (NVIDIA GeForce, NVIDIA NVIDIA RTX, Quadro, NVS, NVIDIA Tesla).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (cryptography), errors and authentication anomalies.
