EUVD-2026-38831

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI endpoint descriptor scans sndusbmidigetmsinfo validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID, but the descriptor walker can still return a class-specific...

CVE-2026-52964 ALSA: usb-audio: Bound MIDI 2.0 endpoint descriptor scans

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI 2.0 endpoint descriptor scans The USB MIDI 2.0 endpoint parser has the same descriptor walking pattern as the legacy MIDI parser. It validates bLength against bNumGrpTrmBlock before reading...

CVE-2026-52964

Summary of CVE-2026-52964 : A flaw in the Linux kernel’s ALSA USB-audio path (USB MIDI 2.0 endpoint parser) fails to validate descriptor lengths for the MIDI 2.0 endpoint, allowing a malformed device to cause out-of-bounds reads on baAssoGrpTrmBlkID[] due to walking endpoint extras before verifyi...
