The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0113 advisory.

  • kernel: vmwgfx: integer overflow in vmwgfx_execbuf.c (CVE-2022-36402)

  • kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)

  • kernel: use after free in unix_stream_sendpage (CVE-2023-4622)

  • kernel: vmwgfx: reference count issue leads to use-after-free in surface handling (CVE-2023-5633)

  • hw amd: Return Address Predictor vulnerability leading to information disclosure (CVE-2023-20569)

  • kernel: netfilter: potential slab-out-of-bound access due to integer underflow (CVE-2023-42753)

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