CVE-2026-31428

CVE-2026-31428 — In the Linux kernel, nfnetlink_log’s __build_packet_message() previously built NFULA_PAYLOAD attributes manually via skb_put()/skb_copy_bits(), bypassing nla_reserve()/nla_put(). This caused trailing padding to remain uninitialized, leaking stale heap data to userspace over NFLOG...

In the Linux kernel, the following vulnerability has been resolved: bridge: mrp: reject zero test interval to avoid OOM panic brmrpstarttest and brmrpstartintest accept the user-supplied interval value from netlink without validation. When interval is 0, usecstojiffies0 yields 0, causing the...

CVE-2026-31420

CVE-2026-31420 affects Linux kernel bridge MRP interval handling. Vulerability arises when br_mrp_start_test/br_mrp_start_in_test accept a user-supplied interval from netlink with no validation; if interval is 0, the delay becomes zero and a tight loop can exhaust memory, causing an OOM kernel pa...
