Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - slab: Avoid race on slab->obj_exts in alloc_slab_obj_exts If two competing threads enter     alloc_slab_obj_exts() and one of them fails to allocate the object extension vector, it might override the     valid slab->obj_exts allocated by the other thread with OBJEXTS_ALLOC_FAIL. This will cause the thread     that lost this race and expects a valid pointer to dereference a NULL pointer later on. Update     slab->obj_exts atomically using cmpxchg() to avoid slab->obj_exts overrides by racing threads. Thanks for     Vlastimil and Suren's help with debugging. (CVE-2025-40348)

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

The remote Oracle Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-50006 advisory.

    - xfrm: delete x->tunnel as we delete x (Sabrina Dubroca)   {CVE-2025-40215}

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
