Echo: linux: security update to 6.1.180-1

high Tenable Cloud Security Plugin ID 459827

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: udc: Fix use-after-free
 in gadget_match_driver The udc structure acts as the management structure for the gadget, but their
 lifecycles are decoupled. A race condition exists where usb_del_gadget() frees the udc memory (e.g., via
 mode-switch work) while gadget_match_driver() concurrently accesses the freed udc memory (e.g., via
 configfs), causing a Use-After-Free (UAF) that triggers a NULL pointer dereference when the freed memory
 is zeroed: [39430.908615][ T1171] Unable to handle kernel NULL pointer dereference at virtual address
 0000000000000000 [39430.911397][ T1171] pc : __pi_strcmp+0x20/0x140 [39430.911441][ T1171] lr :

 this by ensuring the udc structure remains allocated until the gadget is released. To achieve this,
 introduce a new usb_gadget_release() routine to the core. When the gadget is added, usb_add_gadget()
 stores the gadget's release routine in the udc structure and takes a reference to the udc. When the gadget
 is released, usb_gadget_release() drops the reference to the udc and then calls the gadget's release
 routine. (CVE-2026-64346)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
