Background
The nfsd package is a part of the Linux Kernel ecosystem and is responsible for providing support for the Network File System (NFS) server. NFS allows remote clients to access files over a network as if they were local. The nfsd package plays a crucial role in handling NFS requests and managing file sharing. However, a race condition vulnerability has been identified in the nfsd package.
Vulnerability Detail
The race condition vulnerability in the nfsd package can lead to a startup race during the initialization process. This vulnerability was introduced in version v5.12 of the Linux Kernel and fixed in version v5.15.8. The vulnerability can be exploited by an attacker to disrupt the proper startup of the nfsd service, potentially leading to denial of service (DoS) attacks. The impact and attack plausibility of this vulnerability have not been proven yet.
