CVE-2026-74413

The CVE-2026-74413 issue affects the Linux kernel wifi driver rtW89, where AER error handlers incorrectly retrieved a pointer stored with pci_set_drvdata as a net_device instead of the ieee80211_hw pointer, causing operations on the wrong offsets in netif_device_detach/attach. The fix aligns the ...

CVE-2026-74411

The CVE affects the Linux kernel with the wifi driver rtw89 (rtw89_core). The vulnerability arises in the 6 GHz scan path where the 6GHz channel-list scan loop uses an incorrect data type for the scan index, leading to an infinite/long loop and a soft lockup (CPU stuck for ~26s) during wifi scans...

CVE-2026-74409 wifi: rtw89: add bounds check on firmware mac_id in link lookup

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: add bounds check on firmware macid in link lookup The macid field in RX descriptors is 8 bits wide 0-255, but assoclinkonmacid has only RTW89MAXMACIDNUM 128 entries. While the driver currently assigns macid values...

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...
