CVE-2024-58077 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ASoC: soc-pcm: don’t use soc_pcm_ret() on .prepare callback

commit 1f5664351410 (\ASoC: lower o backend DAIs enabled for … Port\nlog severity) ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions ignoring -EINVAL is over-kill.

The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don’t want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace.

So don’t use soc_pcm_ret() on .prepare callback is better idea.
