In the Linux kernel, the following vulnerability has been resolved: xfrm: xfrm_alloc_spi shouldn't use 0 as SPI x->id.spi == 0 means "no SPI assigned", but since commit 94f39804d891 ("xfrm: Duplicate SPI Handling"), we now create states and add them to the byspi list with this value. __xfrm_state_delete doesn't remove those states from the byspi list, since they shouldn't be there, and this shows up as a UAF the next time we go through the byspi list.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1254 advisory.

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

The remote Oracle Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2025-20719 advisory.

    - futex: Prevent use-after-free during requeue-PI (Sebastian Andrzej Siewior)  [Orabug: 38572943]     {CVE-2025-39977}

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.

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

  - xfrm: xfrm_alloc_spi shouldn't use 0 as SPI x->id.spi == 0 means no SPI assigned, but since commit     94f39804d891 (xfrm: Duplicate SPI Handling), we now create states and add them to the byspi list with     this value. __xfrm_state_delete doesn't remove those states from the byspi list, since they shouldn't be     there, and this shows up as a UAF the next time we go through the byspi list. (CVE-2025-39965)

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