Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the interaction between wait for device probe() and deferred probe timeout. The issue caused mounting NFS rootfs to time out when deferred probe timeout was non-zero. This was due to ip auto config() initcall timing out while waiting for network interfaces to appear. Although a commit tried to fix this by making wait for device probe() wait for deferred probe timeout to expire, it introduced a deadlock or blocked kernel init() from continuing until the timeout expired. The changes to wait for device probe() were reverted to resolve the issue.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
