Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 459336

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: Handle probe errors
 properly The probe procedure of setup_card() in caiaq driver doesn't treat the error cases gracefully,
 e.g. the error from snd_card_register() calls snd_card_free() but continues. This would lead to a UAF for
 the further calls like snd_usb_caiaq_control_init(), as Berk suggested in another patch in the link below.
 However, the problem is not only that; in general, this function drops the all error handlings (as it's a
 void function) although its caller can propagate an error to snd_probe(), which eventually calls
 snd_card_free() as a proper error path. That said, we should treat each error case in setup_card(), and
 just return the error code promptly, which is then handled later as a fatal error in snd_probe(). This
 patch achieves it by changing the setup_card() to return an error code. Also, the superfluous
 snd_card_free() call is removed, too. Note that card->private_free can be set still safely at returning an
 error. All called functions in card_free() have checks of the unassigned resources or NULL checks.
 (CVE-2026-46004)

Solution

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