libbpf 0.6.0 and 0.6.1 has a heap-based buffer overflow (4 bytes) in __bpf_object__open (called from bpf_object__open_mem and bpf-object-fuzzer.c).

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libbpf: heap-based buffer overflow (8 bytes) in __bpf_object__open (CVE-2021-45941)

  - libbpf 0.6.0 and 0.6.1 has a heap-based buffer overflow (4 bytes) in __bpf_object__open (called from     bpf_object__open_mem and bpf-object-fuzzer.c). (CVE-2021-45940)

  - A vulnerability was found in Linux Kernel. It has been classified as problematic. This affects the     function find_prog_by_sec_insn of the file tools/lib/bpf/libbpf.c of the component BPF. The manipulation     leads to null pointer dereference. It is recommended to apply a patch to fix this issue. The identifier     VDB-211749 was assigned to this vulnerability. (CVE-2022-3606)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5759-1 advisory.

    It was discovered that LibBPF incorrectly handled certain memory operations under certain circumstances.
    An attacker could possibly use this issue to cause LibBPF to crash, resulting in a denial of service, or     possibly execute arbitrary code. This issue only affected Ubuntu 22.10. (CVE-2021-45940, CVE-2021-45941,     CVE-2022-3533)

    It was discovered that LibBPF incorrectly handled certain memory operations under certain circumstances.
