Summary
CVE-2026-80826 affecting package kernel 6.6.150.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

USB: c67x00: fix use-after-free in c67x00addiso_urb()

When TD creation fails for the last packet of an isochronous URB, c67x00addiso_urb() gives the URB back before updating the endpoint scheduling state.

c67x00givebackurb() frees the URB private data, and the completion callback may release the final URB reference. The following accesses to urbp->ep_data, urb->interval, and urbp->cnt can therefore use freed memory.

Update next_frame and cnt before giving back the failed final packet, making the giveback the last operation that uses the URB and its private data.
