CVE-2026-90229

Estado: RecibidaAlta (7.4)—

In the Linux kernel, the following vulnerability has been resolved:

nvme-apple: Destroy the admin queue on removal

The admin queue is allocated with blk_mq_alloc_queue() but never destroyed. nvme_free_ctrl() only drops the last reference and blk_mq_exit_queue() and blk_sync_queue() never run: the hctx is never moved to q->unused_hctx_list and the timeout timer and work stay armed on a queue that is about to be freed which will eventually oops inside blk_mq_timeout_work().

This can only be triggered when the controller fails to come up and is then immediately torn down again which is why no one ever ran into this before.

Let's just copy what the pcie driver does: unquiesce and destroy the admin queue before nvme_uninit_ctrl().

With this the following WARN followed by a panic no longer happens:

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad local (AV:L) en kernel Linux sin privilegios requeridos. Causa DoS mediante pánico/oops en blk_mq_timeout_work() al destruir incorrectamente cola admin NVMe durante desenlace de controlador fallido.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
