NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs package and not the kernel-docs package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
