LIN1025-15953 : Security Advisory - linux - CVE-2026-52964

Created: Jun 25, 2026    Updated: Jul 31, 2026
Resolved Date: Jul 31, 2026
Found In Version: 10.25.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 25
Component/s: Kernel

Description

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 baAssoGrpTrmBlkID[], but not against the remaining bytes in the endpoint-extra scan.  A malformed device can therefore make later baAssoGrpTrmBlkID[] reads consume bytes past the walked descriptor.  Reject zero-length and overlong descriptors while walking endpoint extras.
