CVE-2026-23441

CVE-2026-23441 is a Linux kernel vulnerability in the net/mlx5e driver. The issue is a race condition where the ASO spinlock is released before the hardware finishes processing a WQE, causing a second operation to overwrite a shared DMA context. The fix introduces a private per-object IPSec ASO c...

CVE-2026-23441

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.
