Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5e: Prevent concurrent access to IPSec ASO context<br /> <br /> The query or updating IPSec offload object is through Access ASO WQE.<br /> The driver uses a single mlx5e_ipsec_aso struct for each PF, which<br /> contains a shared DMA-mapped context for all ASO operations.<br /> <br /> A race condition exists because the ASO spinlock is released before<br /> the hardware has finished processing WQE. If a second operation is<br /> initiated immediately after, it overwrites the shared context in the<br /> DMA area.<br /> <br /> When the first operation&amp;#39;s completion is processed later, it reads<br /> this corrupted context, leading to unexpected behavior and incorrect<br /> results.<br /> <br /> This commit fixes the race by introducing a private context within<br /> each IPSec offload object. The shared ASO context is now copied to<br /> this private context while the ASO spinlock is held. Subsequent<br /> processing uses this saved, per-object context, ensuring its integrity<br /> is maintained.
