Linux · Linux Kernel · CVE-2024-57974
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A race condition exists in the Linux kernel's UDP socket handling. When a UDP socket changes its local address while receiving datagrams, there is a period during which a lookup operation might fail to find it. This issue can cause a port unreachable error to be delivered to the client. The problem is noticeable with a socat server in UDP4-LISTEN mode and a client sending datagrams to it. The issue was first observed as a seldom failure in Podman's tests checking UDP functionality.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
