CVE-2026-64078

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

Description An issue exists in the netfilter x tables component where the removal of a table via rmmod prevents userspace from re-instantiating the table during set/getsockopt operations. This occurs because the larval table is removed and the instantiated table is no longer present on the xt pernet table list. The fix introduces xtables unregister table exit() to properly unlink the table from the dying list, free hook operations, and perform audit notifications, replacing the xt unregister table() function.

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