CVE-2026-31734 is a medium severity vulnerability in the Linux kernel's scheduler extension related to BPF (Berkeley Packet Filter) migration handling. The issue arises from a false negative in the is_bpf_migration_disabled() function on systems without CONFIG_PREEMPT_RCU enabled, which could lead to a migration-disabled task being dispatched to a remote CPU, causing a scheduler error. The flaw was fixed by applying a conditional check only when CONFIG_PREEMPT_RCU is enabled to correctly handle task migration status.
