"The remote Oracle Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in
the ELSA-2023-13043 advisory.

  - An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating
    `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since
    `skb_shared_info` contains references to function pointers. (CVE-2023-42752)

  - A use after free issue was discovered in driver/firewire in outbound_phy_packet_callback in the Linux
    Kernel. In this flaw a local attacker with special privilege may cause a use after free problem when
    queue_event() fails. (CVE-2023-3159)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to
    achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane
    transaction and nft_set element garbage collection, it is possible to underflow the reference counter
    causing a use-after-free vulnerability. We recommend upgrading past commit
    3e91b0ebd994635df2346353322ac51ce84ce6d8. (CVE-2023-4244)

  - A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD
    and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`.
    This issue may allow a local user to crash the system. (CVE-2023-42756)

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)
    component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve
    (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call
    vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling
    pointer that can cause a use-after-free. We recommend upgrading past commit
    b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to
    achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending
    network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug
    and lack of error checking in agg_dequeue(). We recommend upgrading past commit
    8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

  - A flaw was found in KVM. An improper check in svm_set_x2apic_msr_interception() may allow direct access to
    host x2apic msrs when the guest resets its apic, potentially leading to a denial of service condition.
    (CVE-2023-5090)

  - An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel
    before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

  - A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a
    logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a malicious local
    privileged user to cause a use-after-free and double-free problem, which may permit remote code execution
    or lead to local privilege escalation problem. (CVE-2023-5178)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to
    achieve local privilege escalation. Addition and removal of rules from chain bindings within the same
    transaction causes leads to use-after-free. We recommend upgrading past commit
    f15f29fd4779be8a418b66e9d52979bb6d6c2325. (CVE-2023-5197)
