CVE-2026-102760

When NetX Secure is built with NXSECUREKEYCLEAR, every TLS record sent on an active session is wiped after it has been handed to TCP. By then the TCP layer owns the packet chain and may already have released it to the packet pool. The wipe therefore writes zeros into packets that are free or in u...

CVE-2026-102716

An unauthenticated client can drain the RTSP server's packet pool with a couple of dozen requests that carry a Session header the parser cannot convert. The Session branch returns the raw NetX error code instead of an RTSP status code: c / addons/rtsp/nxrtspserver.c:2754 / status =...

CVE-2026-102716

An unauthenticated client can cause a Denial of Service (DoS) on an RTSP server by draining its packet pool. The vulnerability exists in the Session branch of the parser within nx_rtsp_server.c, where a failure in _nx_utility_string_to_uint returns a raw NetX error code instead of a proper RTSP s...

When Ethernet bridging is enabled CONFIGNETETHERNETBRIDGE, ethbridgeinputprocess in subsys/net/l2/ethernet/bridge/bridgeinput.c decides how each frame received on a bridge member interface is handled. For frames that must also be delivered to the local stack, the code called ethbridgehandlelocall...

CVE-2026-14366

The Silicon Labs SiWx917 WiFi driver's transmit callback siwx91xsend in drivers/wifi/siwx91x/siwx91xwifi.c frees a network packet it does not own. In the Zephyr TX path the netpkt is owned by the L2/networking stack; the driver only borrows it to copy the frame bytes into a local netbuf. Before t...

mcumgrserialprocessfrag in subsys/mgmt/mcumgr/transport/src/serialutil.c calls netbufreset on the result of smppacketalloc before checking it for NULL. smppacketalloc uses netbufallocKNOWAIT against the shared MCUmgr packet pool CONFIGMCUMGRTRANSPORTNETBUFCOUNT, default 4, which returns NULL when...

CVE-2026-10648

CVE-2026-10648 affects Zephyr’s MCUmgr serial/console SMP transport paths. The bug occurs in mcumgr_serial_process_frag() where net_buf_reset() is invoked on the result of smp_packet_alloc() before checking NULL. smp_packet_alloc() draws from the shared MCUmgr packet pool (default 4 entries) via ...
