CVE-2026-31394

CVE-2026-31394 concerns the Linux kernel mac80211 path where AP_VLAN (4addr) stations can trigger a NULL pointer dereference in __ieee80211_sta_cap_rx_bw() due to sta->sdata pointing to VLAN sdata, which may not participate in chanctx reservations. The root cause is that link->reserved.oper...

CVE-2026-0123

In EfwApTransport::ProcessRxRing of efwaptransport.cc, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...

CVE-2026-28520

arduino-TuyaOpen before version 1.2.1 contains a single-byte buffer overflow vulnerability in the WiFiMulti component. When the victim's smart hardware connects to an attacker-controlled AP hotspot, the attacker can exploit the overflow to execute arbitrary code on the affected embedded device...

CVE-2026-4558

A flaw has been found in Linksys MR9600 2.0.6.206937. Affected is the function smartConnectConfigure of the file SmartConnect.lua. Executing a manipulation of the argument configApSsid/configApPassphrase/srpLogin/srpPassword can lead to os command injection. The attack may be launched remotely. T...

EUVD-2026-12576

A vulnerability was determined in UTT HiPER 810G up to 1.7.7-171114. Affected is the function strcpy of the file /goform/formApLbConfig. This manipulation of the argument loadBalanceNameOld causes buffer overflow. The attack can be initiated remotely. The exploit has been publicly disclosed and m...

CVE-2026-28520

CVE-2026-28520 affects arduino-TuyaOpen prior to 1.2.1, where the WiFiMulti component contains a single-byte buffer overflow. When a device connects to an attacker-controlled AP hotspot, the overflow can be exploited to execute arbitrary code on the embedded device (remote code execution). The av...

CVE-2025-15568

A command injection vulnerability was identified in the web module of Archer AXE75 v1.6/v1.0 router. An authenticated attacker with adjacent-network access may be able to perform remote code execution RCE when the router is configured with sysmode=ap. Successful exploitation results in root-level...
