CVE-2024-40967

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to a potential deadlock in the Linux kernel's serial component, specifically in the imx uart console write() function. By introducing a timeout when waiting for the transmitter to be empty, the kernel avoids this deadlock. If a timeout occurs, the transmitter state is ignored, and the process continues optimistically. This issue may allow an attacker to cause a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
