Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/mlx5: Fix memory leak in GET_DATA_DIRECT_SYSFS_PATH handler

The UVERBS_HANDLER(MLX5_IB_METHOD_GET_DATA_DIRECT_SYSFS_PATH) function

allocates memory for the device path using kobject_get_path(). 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
