The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-1998 advisory.

  - The Linux kernel allows userspace processes to enable mitigations by calling prctl with     PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed     that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to     attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be     observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened     because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that     STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection.
    However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons,     which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target     injection against which STIBP protects. (CVE-2023-1998)

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

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2148-1 advisory.

  - An issue was discovered in the Linux kernel before 5.8. lib/nlattr.c allows attackers to cause a denial of     service (unbounded recursion) via a nested Netlink policy with a back reference. (CVE-2020-36691)

  - A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

  - The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer     overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send     buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer     to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC     message with garbage data is still correctly formed according to the specification and is passed forward     to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the     allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (CVE-2022-43945)

This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

  - A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.

    (CVE-2023-30772)

  - A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in     the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend     upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

  - A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - 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 flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and     font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds     occurs leading to undefined behavior and possible denial of service. (CVE-2023-3161)

  - An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket.

    A double-free vulnerability was found in the handling of IORING_OP_SOCKET operation with io_uring on the     Linux kernel. (CVE-2023-1032)

    Due to a type confusion during initializations, the tun and tap sockets in the Linux Kernel have their     socket UID hardcoded to 0, i.e. root. While it will be often correct, as TUN/TAP devices require     CAP_NET_ADMIN, it may not always be the case. The socket UID may be used for network filtering and     routing, thus TUN/TAP sockets may be incorrectly managed, potentially bypassing network filters based on     UID. (CVE-2023-1076)

    kernel: Type confusion in pick_next_rt_entity(), which can result in memory corruption. (CVE-2023-1077)

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)

    When plain IBRS is enabled (not enhanced IBRS), the logic in spectre_v2_user_select_mitigation()     determines that STIBP is not needed. The IBRS bit implicitly protects against cross-thread branch     targetinjection. However, with legacy IBRS, the IBRS bit is cleared on returning to userspace for     performance reasons which leaves userspace threads vulnerable to cross-thread branch target injection     against which STIBP protects. (CVE-2023-1998)

    A use-after-free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw     could allow a local user to cause a denial of service. (CVE-2023-2985)

    An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker     can trigger a race condition that results in a fill_kobj_path out-of-bounds write. (CVE-2023-45863)

    A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

    It has been discovered that on some AMD CPUs, the RAS (Return Address Stack, also called RAP - Return     Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology) is     dynamically partitioned between non-idle threads.  This allows an attacker to control speculative     execution on the adjacent thread. (CVE-2022-27672)

    The upstream bug report describes this issue as follows:

    A flaw found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The     rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user     can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info`     actually points to something else that is potentially controlled by local user. It is known how to trigger     this, which causes an OOB access, and a lock corruption. (CVE-2023-1078)

    Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation.

    Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were     insufficient in some situations. A local attacker could possibly use this to expose sensitive information.
    (CVE-2023-1998)

    Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the     Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing     credentials. A physically proximate attacker placed between two Bluetooth devices could use this to     subsequently impersonate one of the paired devices. (CVE-2023-24023)

    shanzhulig discovered that the DRM subsystem in the Linux kernel contained a race condition when     performing certain operation while handling driver unload, leading to a use-after-free vulnerability. A     local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2023-51043)

    It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to     a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2023-51779)

    It was discovered that the device mapper driver in the Linux kernel did not properly validate target size     during certain memory allocations. A local attacker could use this to cause a denial of service (system     crash). (CVE-2023-52429, CVE-2024-23851)

    Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly     check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service     (system crash). (CVE-2023-6915)

    It was discovered that the SCTP protocol implementation in the Linux kernel contained a race condition     when handling lock acquisition in certain situations. A local attacker could possibly use this to cause a     denial of service (kernel deadlock). (CVE-2024-0639)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    - Architecture specifics;

    - EDAC drivers;

    - Media drivers;

    - JFS file system; (CVE-2023-52603, CVE-2023-52464, CVE-2023-52600, CVE-2023-52445, CVE-2023-52451)

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

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