CVE-2021-47212

A vulnerability was found in the Linux kernel, affecting the Mellanox MLX5 driver. This issue involves improper error handling in the UCTX (user context) and UMEM (user memory) operations. When the system executes a destroy command during a fast unload flow, it should return a success code (MLX5_CMD_STAT_OK), but in the affected versions, it incorrectly returned an error code (EIO), causing issues in releasing user memory and removing context in the system. This error handling flaw could lead to system instability during device removal or context destruction in the kernel's Infiniband stack.
