CVE-2026-74409

Summary : The CVE-2026-74409 issue resides in the Linux kernel wifi driver for RTW89. An 8‑bit mac_id in RX descriptors (0–255) can index into assoc_link_on_macid[] which has only 128 entries (RTW89_MAX_MAC_ID_NUM). Firmware-supplied mac_id values are not validated before use as an array index, a...
