CVE-2025-40185

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: ice_adapter: release xa entry on adapter allocation failure<br /> <br /> When ice_adapter_new() fails, the reserved XArray entry created by<br /> xa_insert() is not released. This causes subsequent insertions at<br /> the same index to return -EBUSY, potentially leading to<br /> NULL pointer dereferences.<br /> <br /> Reorder the operations as suggested by Przemek Kitszel:<br /> 1. Check if adapter already exists (xa_load)<br /> 2. Reserve the XArray slot (xa_reserve)<br /> 3. Allocate the adapter (ice_adapter_new)<br /> 4. Store the adapter (xa_store)
