    2024-06-19: CVE-2023-52778 was added to this advisory.

    2024-02-01: CVE-2024-0584 was added to this advisory.

    2024-02-01: CVE-2024-0607 was added to this advisory.

    2024-01-03: CVE-2023-6932 was added to this advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    mptcp: deal with large GSO size (CVE-2023-52778)

    In the Linux kernel, the following vulnerability has been resolved:

    bonding: stop the device in bond_setup_by_slave() (CVE-2023-52784)

    In the Linux kernel, the following vulnerability has been resolved:

    ipvlan: add ipvlan_route_v6_outbound() helper (CVE-2023-52796)

    In the Linux kernel, the following vulnerability has been resolved:

    SUNRPC: Fix RPC client cleaned up the freed pipefs dentries (CVE-2023-52803)

    In the Linux kernel, the following vulnerability has been resolved:

    drivers/perf: hisi: use cpuhp_state_remove_instance_nocalls() for hisi_hns3_pmu uninit process
    (CVE-2023-52860)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to
    achieve local privilege escalation.

    The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the
    argument sync is true, making it possible to free a catchall set element many times.

    We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630. (CVE-2023-6111)

    A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve
    local privilege escalation.

    A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object
    which is freed by another thread.

    We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

    A use-after-free issue was found in igmp_start_timer in net/ipv4/igmp.c in the network sub-component in
    the Linux Kernel. This flaw allows a local user to observe a refcnt use-after-free issue when receiving an
    igmp query packet, leading to a kernel information leak. (CVE-2024-0584)

    netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval() (CVE-2024-0607)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
