The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:4447 advisory.

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

Security Fix(es):

* kernel: TIPC message reassembly use-after-free remote code execution vulnerability (CVE-2024-36886)

* kernel: net/sched: act_skbmod: Skip non-Ethernet packets (CVE-2021-47293)

* kernel: net: ti: fix UAF in tlan_remove_one (CVE-2021-47310)

* kernel: KVM: NULL pointer dereference in kvm_mmu_invpcid_gva (CVE-2022-1789)

* kernel: tls: race between async notify and socket close (CVE-2024-26583)

* kernel: tls: race between tx work scheduling and socket close (CVE-2024-26585)

* kernel: ipv6: sr: fix possible use-after-free and null-ptr-deref (CVE-2024-26735)

* kernel: Bluetooth: Avoid potential use-after-free in hci_error_reset (CVE-2024-26801)

* kernel: net: ip_tunnel: prevent perpetual headroom growth (CVE-2024-26804)

* kernel: netfilter: nf_tables: use timestamp to check for set element timeout (CVE-2024-27397)

* kernel: net: ena: Fix incorrect descriptor free behavior (CVE-2024-35958)

* kernel: ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr (CVE-2024-35969)

* kernel: scsi: lpfc: Move NPIV's transport unregistration to after resource clean up (CVE-2024-36952)

* kernel: tls: handle backlogging of crypto requests (CVE-2024-26584)

* kernel: netfilter: nf_tables: honor table dormant flag from netdev release event path (CVE-2024-36005)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

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.
