No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In get_eht_operation_channel_width of ieee802_11_common.c, there is a possible out of bounds read due to an incorrect bounds check. This could lead to remote (proximal/adjacent) information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
