What it is

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

wifi: iwlwifi: mvm: validate TX_CMD response layout

TX_CMD parsing uses frame_count to walk status entries and then

read the trailing SCD SSN. Make the minimum-length check follow

that exact runtime layout calculation before parsing the payload.

For new TX API, reject TX_CMD responses with frame_count != 1 and

warn/return in the aggregation handler to document that aggregated

accounting is expected via BA notifications.
