——2Multiple memory leaks in openNDS before 11.0.0 allow an unauthenticated attacker on the captive portal network to exhaust all available memory on the device within minutes.21hCVE-2026-478887.5 HIG24.8%

——7Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.22hCVE-2026-129995.3 MED5.3%
——2The Infineon Airoc Wi-Fi driver's transmit callback airoc_mgmt_send() in drivers/wifi/infineon/airoc_wifi.c allocates a net_buf from the fixed airoc_pool for every outbound packet. When whd_network_send_ethernet_data() returns a synchronous failure, the underlying WHD library does not take ownership of the buffer, but the pre-fix driver returned -EIO without releasing it. Each failed transmit therefore permanently leaks one buffer from the pool.
airoc_pool is small and fixed (AIROC_WIFI_TX_PACKET_POOL_COUNT + AIROC_WIFI_RX_PACKET_POOL_COUNT, default 20 buffers) and is shared by WHD's whd_host_buffer_get callback for both transmit and receive. Once enough send failures have leaked the pool dry, airoc_wifi_host_buffer_get() returns WHD_BUFFER_ALLOC_FAIL for all subsequent allocations, so both transmit and the WHD-driven receive path fail and Wi-Fi connectivity is lost until the device is rebooted.
The leak occurs only on the transmit error path. A Wi-Fi-adjacent attacker can influence the conditions that cause synchronous send failures (for example by deauthenticating/disassociating the station while the local stack continues to attempt transmits), and ordinary transient failures over the device's lifetime accumulate toward the same state. Reliable on-demand triggering is of high complexity and the impact is availability-only, but the resulting denial of service is permanent and non-recoverable without a reboot.
The fix releases the buffer with airoc_wifi_buffer_release() on the failure branch, returning it to the pool. The commit also removes a redundant k_sem_give() in airoc_mgmt_disconnect(); because data->sema_common is a binary semaphore (limit 1) the duplicate give merely saturated at 1 and had no security impact.4dCVE-2026-762357.5 HIG28.2%
——8A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service.5dCVE-2026-716757.5 HIG31.5%
——9An issue in Open5GS v.2.7.0 allows a remote attacker to cause a denial of service via the ngap_send_to_nas() function in src/amf/ngap-path.c10d
