CVE-2026-53241

Summary: CVE-2026-53241 affects the Linux kernel ALSA sequencer dummy port. A local attacker could trigger a stack overread when handling Universal MIDI Packet (UMP) events due to copying a UMP-sized packet into legacy stack storage, leaving the UMP data truncated. The root cause is the dummy cli...
