EUVD-2026-55593

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: free RNR data on MBSSID mismatch nl80211parsebeacon rejects EMA RNR data when there are fewer RNR entries than MBSSID entries. The rejected RNR allocation has not been attached to the beacon data yet, so free it...

CVE-2026-68373

The CVE-2026-68373 entry documents a Linux kernel vulnerability in the wifi: at76c50x-usb driver, where at76_guess_freq() can underflow when processing beacon and probe response frames. If a frame is shorter than the 36-byte element offset (el_off), the subtraction len -= el_off causes an oversiz...

EUVD-2026-55559

In the Linux kernel, the following vulnerability has been resolved: wifi: at76c50x-usb: avoid length underflow in at76guessfreq at76guessfreq checks only that the received frame is at least a bare 802.11 header 24 bytes before subtracting the fixed management-body offset: len -= eloff; For both...

CVE-2026-68355

The CVE-2026-68355 entry concerns the Linux kernel WiFi ATH11K driver. It describes a potential buffer underflow in ath11k_hal_rx_msdu_list_get() when the first msdu_details entry has a zero buffer address, causing access to msdu_details[i-1] with i == 0. The issue is mitigated by adding a separa...

In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix OOB read from firmware IE lengths in connect event The firmware-controlled beaconielen, assocreqlen, and assocresplen fields in ath6klwmiconnecteventrx are not validated against the buffer length. Their sum up t...

CVE-2026-68326

CVE-2026-68326 (Linux mwifiex bound uAP association event IEs to the event buffer) : The issue arises in the mwifiex driver within the Linux kernel when handling EVENT_UAP_STA_ASSOC. The code exposes the association request IEs (assoc_req_ies) via a length calculation that uses event->len, whi...

CVE-2026-68309

The vulnerability CVE-2026-68309 affects the Linux kernel driver for wifi mt76 (Connac) and fixes a NULL-pointer dereference in mt76_connac_mcu_uni_bss_he_tlv(). The root cause is that mt76_connac_get_he_phy_cap could return NULL, and the code may dereference the cap pointer without checking. A p...

CVE-2026-68308

CVE-2026-68308 details a Linux kernel issue in the mt76 mt7996 driver where the routine mt76_connac_get_he_phy_cap() can theoretically return NULL. The vulnerability arises from dereferencing the cap pointer without validating it first; the fix is to check the pointer before use. The issue has be...

CVE-2026-68199

The CVE concerns the Linux kernel wifi component ath6kl, where aggr_recv_addba_req_evt() does not return when the firmware-supplied win_sz is outside the valid range [AGGR_WIN_SZ_MIN, AGGR_WIN_SZ_MAX]. This causes out-of-range win_sz to be used in TID_WINDOW_SZ() to compute a kzalloc size, storin...

CVE-2026-68195

The CVE describes a Linux kernel issue in the mt76/mt7615 wireless driver where PKT_TYPE_TXRX_NOTIFY is mmio-only but was dispatched on non-mmio buses, causing a NULL dereference when mt7615_mac_tx_free() calls tx_cleanup() with a NULL queue_ops->tx_cleanup(). The fix drops TXRX_NOTIFY on non-...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: rtw88: Fixed an alignment fault in rtwcoreenablebeacon. The rtwcoreenablebeacon function reads 4 bytes from an address that is not a multiple of 4. This results in a crash on some systems. Instead, only 1 byte is...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Wifi: RSI: Do not default to -EOPNOTSUPP in rsimac80211config. This triggers a WARNON in ieee80211hwconfinit, and this is not the expected behavior from the driver. Other drivers also default to 0...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Wifi: rtl8xxxu: Fixed a slab-out-of-bounds issue in rtl8xxxustaadd. The driver does not set hw-stadatasize, which causes mac80211 to allocate insufficient space for the driver’s private station data in stainfoalloc. When...
