CVE-2026-15924

Zephyr's TLS socket layer in subsys/net/lib/sockets/socketstls.c keeps a single process-global array, clientcache, of cached client sessions that is shared by every TLS socket context. The functions that mutate and read it — tlssessionsave, tlssessionget, tlssessioncachereset, and the settings...

CVE-2026-16147

The ITE IT82xx2 USB device-controller driver in Zephyr RTOS (drivers/usb/udc/udc_it82xx2.c) contains a use-after-free caused by premature buffer submission during multi-packet OUT transfers. When a full max-packet-size packet arrives before the buffer is complete, the driver both re-arms the endp...
