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. (NVD)
