CVE-2025-40185

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel where a reserved XArray entry is not released following a failure during adapter allocation within the ice adapter new() function. This can lead to subsequent insertions at the same index returning an error, potentially resulting in NULL pointer dereferences. The issue occurs when ice adapter new() fails after xa insert() has been called, and the reserved XArray entry is not properly released. The recommended resolution involves reordering operations to check for existing adapters, reserve the XArray slot, allocate the adapter, and then store the adapter.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
