The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1306 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * memcg does not limit the number of POSIX file locks allowing memory exhaustion (CVE-2022-0480)

    * vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query (CVE-2022-38096)

    * use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

    * nfp: use-after-free in area_cache_get() (CVE-2022-3545)

    * NULL pointer dereference in can_rcv_filter (CVE-2023-2166)

    * Slab-out-of-bound read in compare_netdev_and_ip (CVE-2023-2176)

    * UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch     requests (CVE-2023-3390)

    * out-of-bounds access in relay_file_read (CVE-2023-3268)

    * vmxnet3: NULL pointer dereference in vmxnet3_rq_cleanup() (CVE-2023-4459)

    * Gather Data Sampling (GDS) side channel vulnerability (CVE-2022-40982,Downfall)

    * net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails (CVE-2023-3609)

    * Race Condition leading to UAF in Unix Socket could happen in sk_receive_queue ()

    * use-after-free in l2cap_sock_release in net/bluetooth/l2cap_sock.c (CVE-2023-40283)

    * use after free in unix_stream_sendpage (CVE-2023-4622)

    * bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe     (CVE-2023-2163)

    * A heap out-of-bounds write when function perf_read_group is called and sibling_list is smaller than its     child's sibling_list (CVE-2023-5717)

    * ktls overwrites readonly memory pages when using function splice with a ktls socket as destination     (CVE-2024-0646)

    * use-after-free in IPv4 IGMP (CVE-2023-6932)

    * GSM multiplexing race condition leads to privilege escalation (CVE-2023-6546,ZDI-CAN-20527)

    * refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)
