CVE-2026-93793 · Severity: high · CVSS 8.8 · Published 2026-09-24

Executive brief

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.
