Overview

CVE-2026-98430 is a known-severity vulnerability. It was published on October 14, 2026.

Technical description

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

RDMA/efa: Keep admin queues alive while IRQ is registered

The management IRQ handler accesses both the admin completion queue and the

async event queue. The driver registered the IRQ before constructing these

queues and destroyed them before freeing the IRQ, so the handler's lifetime

was not contained by the resources it accesses.

Initialize the queues with interrupts masked, request the IRQ, and then

switch to interrupt mode. On removal, reset the device and free the IRQ

before destroying the queues. Also reset the device before destroying the

queues if IRQ registration fails, because the device already has their DMA

addresses.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
