Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 463656

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: ALSA: caiaq: take a reference on the
 USB device in create_card() The caiaq driver stores a pointer to the parent USB device in cdev->chip.dev
 but never takes a reference on it. The card's private_free callback, snd_usb_caiaq_card_free(), can run
 asynchronously via snd_card_free_when_closed() after the USB device has already been disconnected and
 freed, so any access to cdev->chip.dev in that path dereferences a freed usb_device. On top of the
 refcounting issue, the current card_free implementation calls usb_reset_device(cdev->chip.dev). A reset in
 a free callback is inappropriate: the device is going away, the call takes the device lock in a teardown
 context, and the reset races with the disconnect path that the callback is already cleaning up after. Take
 a reference on the USB device in create_card() with usb_get_dev(), drop it with usb_put_dev() in the free
 callback, and remove the usb_reset_device() call. (CVE-2026-31701)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
