CVE: CVE-2026-43208

CVSS: 9.8 (3.1) — CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Severity: CRITICAL

Status: Critical advisory

Affected

_See vendor advisory_

Summary

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

net: do not pass flow_id to set_rps_cpu()

Blamed commit made the assumption that the RPS table for each receive

queue would have the same size, and that it would not change.

Compute flow_id in set_rps_cpu(), do not assume we can use the value

computed by get_rps_cpu(). Otherwise we risk out-of-bound access

and/or crashes.
