Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： wifi: iwlwifi: mvm: 在 BA 窗口状态通知中验证 sta_id BA_WINDOW_STATUS_NOTIFICATION_ID 从固件通知中提取一个 5 位的 sta_id，并将其用作 fw_id_to_mac_id[] 数组的索引，但此前未进行边界检查。在访问数组前对 sta_id 进行验证，以防止越界索引。
