Echo: linux: security update to 6.1.147-1

medium Tenable Cloud Security Plugin ID 457469

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: pcm: Fix race of buffer access
 at PCM OSS layer The PCM OSS layer tries to clear the buffer with the silence data at initialization (or
 reconfiguration) of a stream with the explicit call of snd_pcm_format_set_silence() with
 runtime->dma_area. But this may lead to a UAF because the accessed runtime->dma_area might be freed
 concurrently, as it's performed outside the PCM ops. For avoiding it, move the code into the PCM core and
 perform it inside the buffer access lock, so that it won't be changed during the operation.
 (CVE-2025-38078)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
