In the Linux kernel, the following vulnerability has been resolved: can: peak_usb: fix use after free bugs After calling peak_usb_netif_rx_ni(skb), dereferencing skb is unsafe. Especially, the can_frame cf which aliases skb memory is accessed after the peak_usb_netif_rx_ni(). Reordering the lines solves the issue.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986725 advisory.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.

  - can: peak_usb: fix use after free bugs After calling peak_usb_netif_rx_ni(skb), dereferencing skb is     unsafe. Especially, the can_frame cf which aliases skb memory is accessed after the     peak_usb_netif_rx_ni(). Reordering the lines solves the issue. (CVE-2021-47670)

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

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:01983-1 advisory.

    The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security bugfixes.
