Summary

In the 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.

Risk Assessment

An attacker with System privileges could exploit this vulnerability to gain higher privileges on the system. However, it requires prior access to System privileges, which limits the attack vector.

Recommendation

Apply the patch identified as Patch ID: WCNCR00441511 provided by the WLAN driver vendor. Update the driver software to a version containing this fix.
