In the Linux kernel, the following vulnerability has been resolved: devlink: fix possible use-after-free and memory leaks in devlink_init() The pernet operations structure for the subsystem must be registered before registering the generic netlink family. Make an unregister in case of unsuccessful registration.

——4Use-After-Free vulnerability in a zircon kernel pager proxy (Fuchsia), which could lead to a Privilege Escalation from Userspace to Kernel (AP)3dCVE-2026-783768.8 HIG19.6%
——6A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory handling and result in memory corruption.2dCVE-2026-592955.9 MED16.1%
——5Micrometer-instrumented Apache HttpAsyncClient (4.x or 5.x) usage via MicrometerHttpClientInterceptor can leak memory unboundedly when asynchronous requests fail before receiving a response (e.g. connection resets or timeouts). Tracking state for these requests remains in memory indefinitely, and sustained failures lead to heap exhaustion and OutOfMemoryError crashes.3dCVE-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.2dCVE-2026-772357.3 HIG1.4%
——0Missing privilege verification in the secure context cleanup handler in FreeRTOS-Kernel before 11.3.1 might allow local users to cause a use-after-free condition in secure-world memory via the SVC handler for secure context deallocation. To remediate this issue, users should upgrade to version 11.3.1 or later.2dCVE-2026-399098.1 HIG52.9%
——16llama.cpp before b8585 contains a use-after-free vulnerability in the RPC server's GRAPH_RECOMPUTE handler that allows unauthenticated remote attackers to achieve arbitrary read and write access by storing a computation graph, freeing referenced buffers, and reclaiming freed memory with attacker-controlled content. Attackers can send RPC requests to trigger re-execution of stored graphs with dangling pointers, enabling full remote code execution without requiring authentication or user interaction.3d
