CVE-2026-13343

CVE-2026-13343 affects the Zephyr RTOS UMP Stream responder library (lib/midi2/ump_stream_responder.c). The functions make_endpoint_info() and make_function_block_info() declare a local struct midi_ump without initialisation, populating only the first two of four uint32_t words. The remaining two...

CVE-2026-74642

A flaw was found in the ALSA USB MIDI2 EPs component of the Linux kernel. This use-after-free UAF vulnerability occurs due to a delayed release of MIDI2 endpoints, leading to an attempt to dereference an already freed Universal MIDI Packet UMP endpoint object. An attacker could potentially exploi...
