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.
Affected configurations
• linux linux kernel (>= 6.12 < 6.12.75)
• linux linux kernel (>= 6.13 < 6.18.14)
• linux linux kernel (>= 6.19 < 6.19.4)
