* kernel: NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852)

* kernel: use after free flaw in l2cap_conn_del in net/bluetooth/l2cap_core.c (CVE-2022-3640)

* kernel: Information leak in l2cap_parse_conf_req in net/bluetooth/l2cap_core.c (CVE-2022-42895)

* kernel: veth: ensure skb entering GRO are not cloned. (CVE-2021-47099)

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.
