Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/mlx5: Fix memory leak in GET_DATA_DIRECT_SYSFS_PATH handler<br /> <br /> The UVERBS_HANDLER(MLX5_IB_METHOD_GET_DATA_DIRECT_SYSFS_PATH) function<br /> allocates memory for the device path using kobject_get_path(). If the<br /> length of the device path exceeds the output buffer length, the function<br /> returns -ENOSPC but does not free the allocated memory, resulting in a<br /> memory leak.<br /> <br /> Add a kfree() call to the error path to ensure the allocated memory is<br /> properly freed.<br /> <br /> Compile tested only. Issue found using a prototype static analysis tool<br /> and code review.
