- 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. (CVE-2026-45922)
