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

  - bpf: Mark syscall helpers as sleepable bpf_sys_bpf() executes the bpf(2) syscall body, which can take     mutexes, allocate with GFP_KERNEL, and wait for an RCU grace period. bpf_sys_close() reaches close_fd()     and filp_close(), which can sleep as well. Both helpers are limited to BPF_PROG_TYPE_SYSCALL, whose main     program is sleepable. That does not make every callback sleepable: a syscall program can register a     bpf_timer callback, and the verifier checks that callback in a non-sleepable context while retaining the     syscall helper set. Without .might_sleep on the prototypes, such a callback can invoke bpf_sys_bpf() from     hrtimer softirq context and trigger a scheduling-while-atomic failure. bpf_sys_close() is exposed through     the same missing context check. Set .might_sleep on both prototypes so the existing helper-context check     rejects them from timer callbacks and other atomic regions. Calls from the sleepable main body remain     valid. (CVE-2026-98058)

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