The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: sched_ext: Fix     is_bpf_migration_disabled() false negative on non-PREEMPT_RCU Since commit 8e4f0b1ebcf2 (bpf: use     rcu_read_lock_dont_migrate() for trampoline.c), the BPF prolog (__bpf_prog_enter) calls migrate_disable()     only when CONFIG_PREEMPT_RCU is enabled, via rcu_read_lock_dont_migrate(). Without CONFIG_PREEMPT_RCU, the     prolog never touches migration_disabled, so migration_disabled == 1 always means the task is truly     migration-disabled regardless of whether it is the current task. The old unconditional p == current check     was a false negative in this case, potentially allowing a migration-disabled task to be dispatched to a     remote CPU and triggering scx_error in task_can_run_on_remote_rq(). Only apply the p == current     disambiguation when CONFIG_PREEMPT_RCU is enabled, where the ambiguity with the BPF prolog still exists.
    (CVE-2026-31734)

Note that Nessus relies on the presence of the package as reported by the vendor.
