Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.0.0-rc3 for upstream debug 2022 08 30 13 10
Description
The Linux kernel contains a flaw in the mlx5 module related to asynchronous command handling. Specifically, a race condition in
mlx5 cmd cleanup async ctx and mlx5 cmd exec cb handler could lead to a use-after-free condition. This occurs when mlx5 cmd cleanup async ctx returns before all callback handlers are completed, potentially freeing memory that is still in use by mlx5 cmd exec cb handler. The issue was identified through KASAN testing, which revealed a read of freed memory during interrupt handling. The root cause is a lack of proper synchronization when managing asynchronous command contexts.Recommendations
Versions prior to 6.0.0-rc3 for upstream debug 2022 08 30 13 10 should be updated.
