LIN1025-15952 : Security Advisory - linux - CVE-2026-52963

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 endpoint descriptor scans  snd_usbmidi_get_ms_info() validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID[], but the descriptor walker can still return a class-specific endpoint descriptor whose bLength exceeds the remaining bytes in the endpoint-extra scan.  That leaves later flexible-array reads bounded by bLength, but not by the remaining bytes in the endpoint-extra scan.  Stop walking when bLength is zero or extends past the remaining endpoint-extra scan.
