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...
