CVE-2026-64348
Overview
CVE-2026-64348 is a known-severity vulnerability. It was published on July 25, 2026.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
usb: free iso schedules on failed submit
EHCI and FOTG210 isochronous submits build an ehci_iso_sched before
linking the URB to the endpoint queue, and keep the staged schedule in
urb->hcpriv until iso_stream_schedule() and the link helpers consume it.
If the controller is no longer accessible, or usb_hcd_link_urb_to_ep()
fails, submit jumps to done_not_linked before that handoff happens and
leaks the staged schedule still attached to urb->hcpriv.
Free the staged schedule from done_not_linked when submit fails before
the URB is linked and clear urb->hcpriv after the free.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. As we do not have
