Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 464095

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: f_hid: move list and
spinlock inits from bind to alloc There was an issue when you did the following: - setup and bind an hid
gadget - open /dev/hidg0 - use the resulting fd in EPOLL_CTL_ADD - unbind the UDC - bind the UDC - use the
fd in EPOLL_CTL_DEL When CONFIG_DEBUG_LIST was enabled, a list_del corruption was reported within
remove_wait_queue (via ep_remove_wait_queue). After some debugging I found out that the queues, which
f_hid registers via poll_wait were the problem. These were initialized using init_waitqueue_head inside
hidg_bind. So effectively, the bind function re-initialized the queues while there were still items in
them. The solution is to move the initialization from hidg_bind to hidg_alloc to extend their lifetimes to
the lifetime of the function instance. Additionally, I found many other possibly problematic init calls in
the bind function, which I moved as well. (CVE-2026-31721)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
