Official Description

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

RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()

Sashiko points out that the user can specify WQs sharing the same CQ as a

part of the uAPI and this will trigger the WARN_ON() then go on to corrupt

the kernel.

Just reject it outright and fail the QP creation.

Technical Analysis

CVE-2026-46117 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
