Description
This security bulletin contains information about 1 security vulnerability.
1) Race condition (CVE-ID: CVE-2026-23441)
The vulnerability allows a local user to cause unexpected behavior and incorrect results.
The vulnerability exists due to a race condition in the IPSec ASO context handling in the mlx5e driver when processing concurrent IPSec offload ASO operations. A local user can trigger concurrent query or update operations to cause unexpected behavior and incorrect results.
The issue arises because a shared DMA-mapped context is used for ASO operations and can be overwritten before earlier hardware processing completes.
Remediation
Install update from vendor's website.
