Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the sound subsystem of the Linux kernel and involves incorrect handling of concurrent PCM hw params calls. This can allow an attacker to access confidential data, compromise data integrity, and cause a denial of service. A local user can potentially crash the system or escalate their privileges due to a use-after-free flaw in the sound subsystem. The flaw occurs when a user triggers concurrent calls of PCM hw params, leading to a race condition inside ALSA PCM for other ioctls.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
