Severity ?

4.7 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

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.

If a second operation is\ninitiated immediately after, it overwrites the shared context in the\nDMA area.\n\nWhen the first operation\u0027s completion is processed later, it reads\nthis corrupted context, leading to unexpected behavior and incorrect\nresults.\n\nThis commit fixes the race by introducing a private context within\neach IPSec offload object. The shared ASO context is now copied to\nthis private context while the ASO spinlock is held. Subsequent\nprocessing uses this saved, per-object context, ensuring its integrity\nis maintained."
