CVE-2026-64077

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: move to two-stage removal scheme Like previous patches for xtables, follow same pattern in ebtables. We can't reuse xt helpers: ebttable struct layout is incompatible. table-ops assignment is now done while...

CVE-2026-64076

The CVE concerns the Linux kernel netfilter/bridge eb_tables initialization, specifically a close module init race. Technical details across the documents describe a race condition where sockopts may be exposed globally after nf_register_sockopt() completes, implying that sockopt registration ord...
