Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the netfilter conntrack component where the ct extension genid infrastructure disables all ct extensions for unconfirmed conntracks. This occurs because the infrastructure was intended only for ct helper and ct timeout. Consequently, certain parts of the codebase dereference the ct extension without performing a NULL check, which can lead to a system crash.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
