Overview

CVE-2026-92488 is a high-severity vulnerability. It was published on September 17, 2026 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

RDMA/erdma: complete object teardown when the destroy command fails

erdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and

erdma_destroy_ah() returned early when erdma_post_cmd_wait() failed,

leaking the queue buffers, MTTs, doorbells and the STAG, QPN, CQN and AHN

identifiers. A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and

permanently disables the command queue, so no retry can succeed; the RDMA

core keeps the object after a failed destructor and forced uverbs cleanup

then nulls the pointers, making the resources unreachable.

Warn on failure but release every software-owned resource and return

success, since during terminal destruction the hardware command result is

only diagnostic.

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.
