Echo: linux: security update to 6.1.159-1

medium Tenable Self-Hosted Container Security Plugin ID 462912

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: usb-audio: Fix NULL pointer
 dereference in snd_usb_mixer_controls_badd In snd_usb_create_streams(), for UAC version 3 devices, the
 Interface Association Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If this call fails, a fallback
 routine attempts to obtain the IAD from the next interface and sets a BADD profile. However,
 snd_usb_mixer_controls_badd() assumes that the IAD retrieved from usb_ifnum_to_if() is always valid,
 without performing a NULL check. This can lead to a NULL pointer dereference when usb_ifnum_to_if() fails
 to find the interface descriptor. This patch adds a NULL pointer check after calling usb_ifnum_to_if() in
 snd_usb_mixer_controls_badd() to prevent the dereference. This issue was discovered by syzkaller, which
 triggered the bug by sending a crafted USB device descriptor. (CVE-2025-40275)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
