wifi: nl80211: clean up color-change beacon data on errors

Assigner: Linux
Reserved: 11.09.2026 Published: 17.09.2026 Updated: 17.09.2026

In the Linux kernel, the following vulnerability has been resolved:

wifi: nl80211: clean up color-change beacon data on errors

nl80211_color_change() calls nl80211_parse_beacon() for the beacon_next template, which can allocate params.beacon_next.mbssid_ies and .rnr_ies. A parsing failure returned directly instead of using the out: cleanup, leaking any allocations completed before the error.

Allocate the nested attribute table before parsing beacon_next. Its allocation failure can then return before beacon data exists, while a later parsing failure uses out: to release the parsed data.
