Описание
In the Linux kernel, the following vulnerability has been resolved:
ice: ice_adapter: release xa entry on adapter allocation failure
When ice_adapter_new() fails, the reserved XArray entry created by xa_insert() is not released. This causes subsequent insertions at the same index to return -EBUSY, potentially leading to NULL pointer dereferences.
Reorder the operations as suggested by Przemek Kitszel:
- Check if adapter already exists (xa_load)
- Reserve the XArray slot (xa_reserve)
- Allocate the adapter (ice_adapter_new)
- Store the adapter (xa_store)
