The remote Oracle Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-12682 advisory.

    - dmaengine: idxd: add a write() method for applications to submit work (Nikhil Rao)  [Orabug: 36770955]     {CVE-2024-21823}
    - dmaengine: idxd: add a new security check to deal with a hardware erratum (Arjan van de Ven)  [Orabug:
    36770955]  {CVE-2024-21823}
    - VFIO: Add the SPR_DSA and SPR_IAX devices to the denylist (Arjan van de Ven)  [Orabug: 36770955]     {CVE-2024-21823}

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.

  - In the Linux kernel, the following vulnerability has been resolved: net: netdevsim: don't try to destroy     PHC on VFs PHC gets initialized in nsim_init_netdevsim(), which is only called if (nsim_dev_port_is_pf()).
    Create a counterpart of nsim_init_netdevsim() and move the mock_phc_destroy() there. This fixes a crash     trying to destroy netdevsim with VFs instantiated, as caught by running the devlink.sh test: BUG: kernel     NULL pointer dereference, address: 00000000000000b8 RIP: 0010:mock_phc_destroy+0xd/0x30 Call Trace: <TASK>     nsim_destroy+0x4a/0x70 [netdevsim] __nsim_dev_port_del+0x47/0x70 [netdevsim]     nsim_dev_reload_destroy+0x105/0x120 [netdevsim] nsim_drv_remove+0x2f/0xb0 [netdevsim]     device_release_driver_internal+0x1a1/0x210 bus_remove_device+0xd5/0x120 device_del+0x159/0x490     device_unregister+0x12/0x30 del_device_store+0x11a/0x1a0 [netdevsim] kernfs_fop_write_iter+0x130/0x1d0     vfs_write+0x30b/0x4b0 ksys_write+0x69/0xf0 do_syscall_64+0xcc/0x1e0     entry_SYSCALL_64_after_hwframe+0x6f/0x77 (CVE-2024-26587)

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