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...
