Echo: linux: security update to 6.1.180-1

medium Tenable Cloud Security Plugin ID 458765

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: usb: gadget: composite: fix dead empty
 check in the USB_DT_OTG handler The OTG branch of composite_setup() falls back to the first configuration
 when none is selected: if (cdev->config) config = cdev->config; else config =
 list_first_entry(&cdev->configs, struct usb_configuration, list); if (!config) goto done; ...
 memcpy(req->buf, config->descriptors[0], value); list_first_entry() never returns NULL. On an empty list
 it returns container_of() of the list head. So the "if (!config)" check is dead. When cdev->configs is
 empty, config points at the head inside struct usb_composite_dev. config->descriptors[0] reads whatever
 sits at that offset. The memcpy copies up to w_length bytes of it into the response buffer. cdev->configs
 can be empty in two cases. One is a teardown race on gadget unbind with a control transfer in flight. The
 other is a driver that sets is_otg before it adds a config. A reproducer that holds cdev->configs empty
 triggers a KASAN fault in this branch. Use list_first_entry_or_null() so the existing check does its job.
 (CVE-2026-64347)
