      * kernel: wifi: rtw88: fix the 'para' buffer size to avoid reading out of bounds (CVE-2025-38159)

Tenable has extracted the preceding description block directly from the AlmaLinux 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 Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:13589 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.
