AI-suggested
A fix is available that moves the sched_node_ids xarray out of the port_info structure and adds the missing xa_destroy call in the cleanup path. Users should apply the updated Linux kernel versions containing this patch to resolve the memory leak. Since this is a kernel driver fix, updating the kernel to a patched version is the recommended remediation.
Description
A memory leak vulnerability was identified and resolved in the Linux kernel's ice driver. The issue stemmed from a missing call to xa_destroy on a sched_node_ids xarray embedded in the port_info structure, causing internal memory allocated by the xarray not to be freed properly. The fix involved moving sched_node_ids out of port_info into the hw structure and adding the missing xa_destroy call during cleanup to ensure proper memory release.
