Echo: linux: security update to 6.12.85-1

medium Tenable Self-Hosted Container Security Plugin ID 459106

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: don't call
 cdev_init while cdev in use When calling unbind, then bind again, cdev_init reinitialized the cdev, even
 though there may still be references to it. That's the case when the /dev/hidg* device is still opened.
 This obviously unsafe behavior like oopes. This fixes this by using cdev_alloc to put the cdev on the
 heap. That way, we can simply allocate a new one in hidg_bind. (CVE-2026-31606)

Solution

Update the linux library and its related packages to version 6.12.85-1 or later.
