CVE-2026-98334

A flaw was found in the Linux kernel's mac80211 wireless subsystem. When starting a wireless Access Point AP fails after setting beacon parameters, the kernel does not properly reset its internal state. A local attacker can exploit this condition by triggering subsequent scanning operations on th...

CVE-2026-98333

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When bringing up a wireless interface fails, the system does not reset the radio LED state, leaving an internal throughput timer running. Consequently, when the wireless device is subsequently removed or unregistered,...

CVE-2026-98331

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When a network namespace hosting a wireless device is destroyed, memory allocation failures during device migration can leave unregistered network interfaces in internal tracking lists. A local user can exploit this...

CVE-2026-98329

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When packets are injected on a monitor network interface, mac80211 does not verify whether the bandwidth requested in the radiotap header exceeds the operational channel bandwidth before forwarding it to the driver. A...

CVE-2026-98328

A flaw was found in the Linux kernel's mac80211 wireless subsystem. This flaw allows a local user to cause a Denial of Service DoS by initiating a wireless scan on a device supporting 6 GHz High Efficiency HE bands. Because the kernel fails to account for the HE 6 GHz capability element when...

CVE-2026-98327

A flaw was found in the Linux kernel's mac80211 wireless mesh networking subsystem. When leaving or stopping a mesh network while a Channel Switch Announcement CSA is still pending, the kernel fails to reset the switch state and release allocated memory. A local privileged user could exploit this...

CVE-2026-98325

A flaw was found in the Linux kernel's mac80211 wireless subsystem. Transmission control information within packet buffers was not initialized early enough, preventing proper cleanup and error reporting if header construction or buffer resizing fails. A local user could exploit this flaw during...

airtop

airtop 空中的 htop — 一个在终端中实时显示的 802.11 Wi-Fi 射频仪表盘。 airtop 将你周围的 Wi-Fi 流量变为一个实时终端仪表盘 — 显示附近接入点的频谱、每个站点的信号轨迹、帧类型活动信息、RSSI 直方图以及已发现网络的滚动列表，所有这些都通过 eBPF 和盲文/块图形绘制。 !TIP 无需监控模式，无需原始套接字。 airtop 将 eBPF 程序附加到 mac80211/cfg80211，在内核 Wi-Fi 栈中读取 802.11 帧，因此它在你的正常已连接接口上运行，不会断开你的链路。 快速开始 curl -fsSL...

CVE-2026-98332

A flaw was found in the Linux kernel's mac80211 wireless subsystem. The Tunneled Direct Link Setup TDLS code fails to verify whether a station is a direct-link peer rather than an access point before executing TDLS operations. A local attacker can exploit this flaw to cause inconsistent kernel...

CVE-2026-98326

A flaw was found in the Linux kernel's mac80211 wireless subsystem. When an attempt to start a wireless mesh network fails, the channel context is not properly released. A local user could exploit this flaw during network interface removal, leading to driver state inconsistency and a potential...

CVE-2026-98182

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local user with network administration privileges can cause a Denial of Service DoS by configuring an inactive network interface to active monitor mode and then bringing the interface up. Because the required transmit queue is...

CVE-2026-98183

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. An adjacent attacker can trigger an out-of-bounds read by transmitting specially crafted wireless mesh network frames containing empty Path Request PREQ elements. This issue occurs because the kernel reads header field...

DEBIAN-CVE-2026-98346

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't get the radio mask for netdev-less wdevs cfg80211calculatebidata calls rdevgetradiomask with wdev-netdev, which can be NULL and then crashes in mac80211. To avoid that, invert the order of checks since...

AZL-106317 CVE-2026-98336 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't offload TC setup on APVLAN interfaces APVLAN interfaces are purely virtual, so don't try to offload TC setup to drivers. We can't really use the AP interface either since we may not know it all the time, and...

DEBIAN-CVE-2026-98337

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't start a ROC while scanning The ROC work can be pending when a scan starts which requires ROC list to be empty, but that's possible, and then a new ROC can be added to the list and the work will pick it up...

AZL-106065 CVE-2026-98335 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: abort chanswitch when leaving a mesh The code in ieee80211stopmesh leaves CSA active, but leaving the mesh released the channel context, so the CSA finalize work crashes: Oops: general protection fault, probably f...
