CVE-2026-72131 — nvme-apple: Prevent shared tags across queues on Apple A11

In the Linux kernel, the following vulnerability has been resolved: nvme-apple: Prevent shared tags across queues on Apple A11 On Apple A11, tags of pending commands must be unique across the admin and IO queues, else the firmware crashes with "duplicate tag error for tag N", with N being the tag. Apply the existing workaround for M1 of reserving two tags for the admin queue to A11.

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

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.

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 (Linux Linux).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.

What should defenders know first?

CVE-2026-72131 is "nvme-apple: Prevent shared tags across queues on Apple A11", rated Unknown. It affects Linux (Linux); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. EPSS 0.22% 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.
