{"apiVersion":"1.0","identifier":"CVE-2026-74502","description":"In the Linux kernel, the following vulnerability has been resolved: ALSA: ump: fix double free of out_cvts on rawmidi error snd_ump_attach_legacy_rawmidi() allocates the legacy conversion array ump->out_cvts and, on the snd_rawmidi_new() error path, frees it with kfree() but leaves ump->out_cvts pointing at the freed memory. When the endpoint is later torn down, snd_ump_endpoint_free() frees ump->out_cvts a second time, resulting in a double free. The host snd-usb-audio driver attaches the legacy rawmidi for any USB MIDI 2.0 (UMP) device, so a device that makes snd_rawmidi_new() fail reaches this path on enumeration. Clear ump->out_cvts after freeing it on the error path so it is not freed again during teardown.
