CVE-2025-20731

In wlan AP driver, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege (when OceReducedNeighborReport is disabled). User interaction is not needed for exploitation. Patch ID: WCNCR00441511; Issue ID: MSV-4140.
