The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1738-1 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused     by unset skb->mac_header If an AF_PACKET socket is used to send packets through ipvlan and the default     xmit function of the AF_PACKET socket is changed from dev_queue_xmit() to packet_direct_xmit() via     setsockopt() with the option name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and remains     as the initial value of 65535, this may trigger slab-out-of-bounds bugs as following:
    ================================================================= UG: KASAN: slab-out-of-bounds in     ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan] PU: 2 PID: 1768 Comm: raw_send Kdump: loaded Not tainted     6.0.0-rc4+ #6 ardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 all Trace:

    __x64_sys_sendto+0x74/0x90 do_syscall_64+0x3b/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd The root cause     is: 1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW and skb->protocol is not     specified as in packet_parse_headers() 2. packet_direct_xmit() doesn't reset skb->mac_header as     dev_queue_xmit() In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is called. So when     ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which use skb->head + skb->mac_header, out-of-bound     access occurs. This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2() and reset mac     header in multicast to solve this out-of-bound bug. (CVE-2022-48651)

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: fix a memory corruption     iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that if we copy to     iwl_fw_ini_trigger_tlv::data + offset while offset is in bytes, we'll write past the buffer.
    (CVE-2024-26610)

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