- Summary
- RDMA/mlx5: Fix memory leak in GET_DATA_DIRECT_SYSFS_PATH handler
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix memory leak in GETDATADIRECTSYSFSPATH handler
The UVERBSHANDLER(MLX5IBMETHODGETDATADIRECTSYSFSPATH) function allocates memory for the device path using kobjectgetpath(). If the length of the device path exceeds the output buffer length, the function returns -ENOSPC but does not free the allocated memory, resulting in a memory leak.
Add a kfree() call to the error path to ensure the allocated memory is properly freed.
Compile tested only. Issue found using a prototype static analysis tool and code review.
