CVE-2026-68471

In the Linux kernel, the following vulnerability has been resolved: wifi: ieee80211: validate MLE common info length ieee80211mlecommonsize uses the first common-info octet as the common information length for all known MLE types. However, ieee80211mlesizeok only validates that octet for Basic,...

CVE-2026-74411

Summary: CVE-2026-74411 affects the Linux kernel Wi‑Fi driver rtw89 on 6 GHz, where a data type issue in the scan index can cause a soft lockup during scanning. The root cause is in rtw89_hw_scan_add_chan_ax within the 6 GHz scan path; the loop uses i as the counter and reads %bl into %eax, with ...

CVE-2026-68439

A flaw was found in the Linux kernel's Wi-Fi driver for the mt7925 component. This vulnerability arises from a potential NULL-pointer dereference within the mt7925mcubsshetlv function. If the mt76connacgethephycap routine returns a null value, it is not properly checked before being used, which...

CVE-2026-68439 wifi: mt76: mt7925: fix possible NULL-pointer deref in mt7925_mcu_bss_he_tlv()

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: fix possible NULL-pointer deref in mt7925mcubsshetlv mt76connacgethephycap routine can theoretically return NULL so check cap pointer before dereferencing it...

CVE-2026-68308

A flaw was found in the Linux kernel's Wi-Fi driver mt76: mt7996. The mt76connacgethephycap routine can theoretically return a null pointer, which is not properly checked before being dereferenced. This oversight could allow a local attacker to cause a denial of service DoS by triggering a system...

CVE-2026-68363

A flaw was found in the ath9k Wi-Fi driver in the Linux kernel. A race condition exists during the asynchronous firmware loading process and device disconnection. A local attacker, by repeatedly connecting and disconnecting a malicious USB Wi-Fi device that fails firmware download, could trigger ...

CVE-2026-68406

A flaw was found in the cfg80211 component of the Linux kernel's Wi-Fi subsystem. This vulnerability allows the PMSR FTM request parser to accept preamble values outside the defined nl80211 range. An attacker could exploit this by providing malformed input, potentially leading to unexpected syste...

CVE-2026-68353

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. The ath6klwmitxcompleteeventrx function, responsible for handling Wi-Fi messages, does not properly validate the nummsg field provided by the firmware against the buffer length. A malicious or compromised firmware could send an inflated...

CVE-2026-68409

A flaw was found in the mac80211 Wi-Fi driver of the Linux kernel. When an MLO Multi-Link Operation link is removed, the RX statistics per-CPU buffer is freed immediately, while the link container is deferred to RCU Read-Copy-Update. This timing issue can lead to a use-after-free vulnerability,...

CVE-2026-68352

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. The driver does not properly validate the lengths of firmware-controlled information elements IEs during a connect event. This vulnerability allows the sum of these lengths to exceed the allocated buffer, resulting in an out-of-bounds...

CVE-2026-68410

A flaw was found in the Linux kernel's Libertas Wi-Fi driver. The helperfirmwarecb function neglects to free a single-stage firmware image after a successful asynchronous load. This leads to a memory leak in the USB firmware-download path. This issue could potentially lead to system instability o...

CVE-2026-68190

A flaw was found in the Linux kernel's rtl8723bs Wi-Fi driver. The rtwgetwpsie function, responsible for processing network frame data, fails to properly validate the size of incoming information elements IEs. This oversight allows an attacker to trigger an out-of-bounds read, potentially leading...

CVE-2026-68412

A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the cfg80211 component. This vulnerability, located in the cfg80211wextsiwscan function, can lead to a memory leak. A local attacker could exploit this by sending a crafted Wi-Fi scan request with an Extended Service Set...

CVE-2026-68402

A flaw was found in the Linux kernel's Wi-Fi subsystem cfg80211. The cfg80211iselementinherited function does not properly validate the length of extension elements.
