In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent concurrent access to IPSec ASO context The query or updating IPSec offload object is through Access ASO WQE. The driver uses a single mlx5e_ipsec_aso struct for each PF, which contains a shared DMA-mapped context for all ASO operations. A race condition exists because the ASO spinlock is released before the hardware has finished processing WQE. If a second operation is initiated immediately after, it overwrites the shared context in the DMA area. When the first operation's completion is processed later, it reads this corrupted context, leading to unexpected behavior and incorrect results. This commit fixes the race by introducing a private context within each IPSec offload object. The shared ASO context is now copied to this private context while the ASO spinlock is held. Subsequent processing uses this saved, per-object context, ensuring its integrity is maintained.
AI Analysis
Technical Summary
CVE-2026-23441 addresses a race condition in the Linux kernel mlx5e driver related to IPSec offload object (ASO) context handling. The driver used a single shared DMA-mapped context for all ASO operations per physical function (PF). Because the ASO spinlock was released before hardware completion of a work queue element (WQE), a subsequent operation could overwrite this shared context. When the first operation completed, it would read corrupted context data, causing unexpected behavior and incorrect results. The patch introduces a private context per IPSec offload object, copying the shared context while holding the spinlock, ensuring data integrity during asynchronous processing.
Potential Impact
The vulnerability can lead to denial of service through corrupted IPSec offload processing results. It does not impact confidentiality or integrity directly but causes availability issues due to unexpected behavior in the network driver. The CVSS score is 4.7 (medium severity) with attack vector local, high attack complexity, low privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, and high impact on availability.
Mitigation Recommendations
An official patch is available and should be applied. The vulnerability is fixed in Linux kernel versions 6.8.0 and later, including specific builds for Ubuntu 22.04 LTS and related releases. Users should update their systems to the fixed kernel versions and reboot to apply the changes. Due to ABI changes, recompilation and reinstallation of third-party kernel modules may be required. No additional mitigations are indicated beyond applying the official fix.
