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.
kernel: local privileges escalation in kernel/bpf/verifier.c (CVE-2022-23222)
Kernel: use-after-free in btf_dump_name_dups in tools/lib/bpf/btf_dump.c (CVE-2022-3534)
An issue was discovered in the Linux kernel through 5.2.13. nbd_genl_status in drivers/block/nbd.c does not check the nla_nest_start_noflag return value. (CVE-2019-16089)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
