How to fix?

Upgrade RHEL:10 kernel-debuginfo-common-ppc64le to version 0:6.12.0-124.20.1.el10_1 or higher.
This issue was patched in RHSA-2025:22854.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debuginfo-common-ppc64le package and not the kernel-debuginfo-common-ppc64le package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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:

  1. Check if adapter already exists (xa_load)
  2. Reserve the XArray slot (xa_reserve)
  3. Allocate the adapter (ice_adapter_new)
  4. Store the adapter (xa_store)
