Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.0.8
Description
The issue is related to the implementation of the Siemens R3964 protocol driver in the Linux kernel, specifically in the drivers/tty/n r3964.c file. It involves errors in synchronization when using a shared resource, known as a "race condition". Exploitation of this issue could allow an attacker to cause a denial of service.
Recommendations
For Linux kernel versions prior to 5.0.8, update to version 5.0.8 or later to resolve the issue.
As a temporary workaround, consider restricting access to the vulnerable driver to minimize the risk of exploitation.
