CVE-2026-14366 1 Zephyrproject 1 Zephyr 2026-09-01 6.4 Medium
The Silicon Labs SiWx917 WiFi driver's transmit callback siwx91x_send() in drivers/wifi/siwx91x/siwx91x_wifi.c frees a network packet it does not own. In the Zephyr TX path the net_pkt is owned by the L2/networking stack; the driver only borrows it to copy the frame bytes into a local net_buf. Before the fix, after transmitting, siwx91x_send() additionally called net_pkt_unref(pkt) on the caller-owned packet, dropping its last reference and returning it to the shared packet pool prematurely. This code path is compiled in by default (CONFIG_WIFI_SILABS_SIWX91X_NET_STACK_NATIVE). The caller, ethernet_send() in subsys/net/l2/ethernet/ethernet.c, keeps using the packet after the driver returns: it reads net_pkt_get_len(pkt), updates TX statistics, and then performs its own net_pkt_unref(pkt). Because the driver already released the packet, these are use-after-free reads followed by a second unref (a double free). When concurrent network activity recycles the freed slab slot between the two unrefs, the trailing unref decrements a different, live packet's reference count and frees it, corrupting the net_pkt pool shared by both the receive and transmit paths. The defect is exercised by ordinary transmission over the native-stack SiWx917 WiFi interface, and an adjacent attacker on the same WiFi network can induce transmissions (for example ARP or ICMP echo replies, or TCP handshakes) to drive the path. The primary observable impact is loss of availability (transmit hangs and crashes from pool corruption), with race-dependent memory corruption of the kernel networking buffer pool. The fix removes the erroneous net_pkt_unref(pkt) from siwx91x_send(); the driver's receive-path unref, which correctly frees a packet the driver itself allocated, is unaffected.
CVE-2026-42007 1 Open-xchange 2 Ox Dovecot Ce, Ox Dovecot Pro 2026-09-01 9.1 Critical
An attacker that has valid credentials can use a Sieve script with the editheader extension to trigger a use-after-free in the mail editing code, and to write memory contents beyond the intended buffer into the delivered mail. This causes memory leak and opportunity to do memory corruption during mail delivery, which can crash the delivery process and may allow execution of arbitrary code in the context of that process. Disable the Sieve editheader extension. Update to non-vulnerable version. No publicly available exploits are known.
CVE-2026-24099 1 Intel 19 Intel Proset Wireless Wifi Software For Windows, Killer Wi-fi 6 Ax1650i\/s, Killer Wi-fi 6e Ax1675i\/s and 16 more 2026-09-01 5.1 Medium
Use after free for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 0: Kernel may allow a denial of service. System software adversary with an unauthenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
CVE-2026-81934 1 Redis 1 Redis 2026-08-31 7.1 High
Redis contains a use-after-free vulnerability in the 'tlsProcessPendingData()' function, which handles the TLS pending-data list if Redis is configured with TLS support. A remote, unauthenticated attacker may be able to execute arbitrary commands with the privileges of the Redis server.
CVE-2026-82623 1 Open62541 1 Open62541 2026-08-31 5.3 Medium
A vulnerability was detected in open62541 up to 1.5.5. Affected by this vulnerability is the function UA_DataValue_backend_copyRange of the file plugins/historydata/ua_history_data_backend_memory.c of the component History Backend. The manipulation results in use after free. The attack can be launched remotely. The exploit is now public and may be used. The project closed the issue report, stating that this is not the official way to report a security vulnerability.
CVE-2026-82619 1 Systerel 1 S2opc 2026-08-31 4.3 Medium
A vulnerability was identified in Systerel S2OPC up to 1.7.3. The impacted element is the function monitored_item_event_filter_treatment_bs__init_event_filter_ctx_and_result of the file src/ClientServer/services/bgenc/subscription_mgr.c. Such manipulation of the argument EventFilter leads to use after free. The attack may be performed from remote. The exploit is publicly available and might be used. The name of the patch is a4cee16a851b971be447a6ed531173702c722b99. It is best practice to apply a patch to resolve this issue.
CVE-2026-77358 1 Yhirose 1 Cpp-httplib 2026-08-31 N/A
cpp-httplib is a C++ header-only HTTP/HTTPS library. In versions 0.33.0 through 0.50.0, the TLS-enabled WebSocket client frees the TLS session before closing the WebSocket that still uses it, producing a use-after-free. In WebSocketClient::shutdown_and_close the SSL object is freed and the pointer cleared, but the subsequent WebSocket close still sends a close frame through the SSL socket stream, which holds a raw copy of the now-dangling session pointer and reads from and writes to the freed memory. The same freed-then-used ordering is reachable through the client's destructor and its connect path, so ordinary teardown of a secure WebSocket connection triggers the defect. This issue is fixed in version 0.50.1.
CVE-2026-76921 1 Wireshark 1 Wireshark 2026-08-31 5.5 Medium
CMS protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service
CVE-2026-58083 1 Freebsd 1 Freebsd 2026-08-31 8.4 High
While the kernel was copying knotes during fork, a knote with a timer-based filter could fire and be enqueued on the kqueue's active list before the copy was complete. The copy routine did not account for this and could enqueue the new knote a second time, corrupting the active list. In addition, the copy routine did not hold the appropriate locks while reading knote state, allowing further races. An unprivileged local user can trigger a use-after-free in the kernel, potentially leading to privilege escalation.
