High Access control

CVE-2025-11901 — Improper Access Control in ASUS B460 series

An uncontrolled resource consumption vulnerability affects certain ASUS motherboards using Intel B460, B560, B660, B760, H410, H510, H610, H470, Z590, Z690, Z790, W480, W680 series chipsets. Exploitation requires physical access to internal expansion slots to install a specially crafted device and supporting software utility, and may lead to uncontrolled resource consumption that increases the risk of unauthorized direct memory access (DMA). Refer to the 'Security Update for UEFI firmware' section on the ASUS Security Advisory for more information.

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

EPSS 0.2% (30-day exploitation probability)+2
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 (ASUS B460 series, ASUS B560 series, ASUS B660 series…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

What should defenders know first?

CVE-2025-11901 is "Improper Access Control in ASUS B460 series", rated High. It affects B460 series (ASUS); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.0 describes technical severity. EPSS 0.23% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
