Vulnerability from fkie_nvd - Published: 2026-05-28 10:16 - Updated: 2026-06-30 03:20

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.0 (High) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

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.
