EUVD-2026-59556

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

The CVE-2026-74409 issue concerns the Linux kernel WiFi driver rt w89. A bounds check was added to prevent out-of-range firmware values in the mac_id field used during link lookup. The mac_id is 8-bit (0–255) while assoc_link_on_macid[] has only RTW89_MAX_MAC_ID_NUM (128) entries, and the descrip...

CVE-2022-49471 rtw89: cfo: check mac_id to avoid out-of-bounds

In the Linux kernel, the following vulnerability has been resolved: rtw89: cfo: check macid to avoid out-of-bounds Somehow, hardware reports incorrect macid and pollute memory. Check index before we access the array. UBSAN: array-index-out-of-bounds in rtw89/phy.c:2517:23 index 188 is out of rang...

CVE-2022-49471

CVE-2022-49471 affects the Linux kernel rtw89 driver (rtw89_core/rtw89_pci). The root cause is a bounds check failure in CFO parsing where an incorrect mac_id can cause an out‑of‑bounds access, triggering UBSAN warning: “array-index-out-of-bounds” in rtw89/phy.c:2517:23 (index 188 vs. 64). This c...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from a failure to check macid in the rtw89phycfoparse function, resulting in an array out-of-bounds...

GSD-2022-1002752 rtw89: cfo: check mac_id to avoid out-of-bounds

rtw89: cfo: check macid to avoid out-of-bounds This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.18.3 by commit...
