EUVD-2026-64347

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtnflog: pin the NFLOG backend nflogunregister runs after the per-net teardown so its final RCU grace period also drains readers that obtained the logger from a per-net binding. However, ebtnflog passes an explicit UL...

CVE-2026-74636

CVE-2026-74636 is a race condition in the Linux kernel tracing subsystem. When two modules are loaded concurrently on different CPUs, event_define_fields() and update_event_fields() can access class->fields simultaneously without proper mutual exclusion. Specifically, trace_event_update_all() ...
