The version of kernel installed on the remote host is prior to 4.14.309-231.529. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1987 advisory.

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

    net: sched: fix memory leak in tcindex_set_parms (CVE-2022-50396)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0458)

    Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root.This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

    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)

    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 iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in the SCSI     sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information.
    (CVE-2023-2162)

    In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

    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)

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the 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 drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux     kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)

The version of kernel installed on the remote host is prior to 5.4.235-144.344. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-043 advisory.

    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)

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

    netfilter: nft_tproxy: restrict to prerouting hook (CVE-2022-50001)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0458)

    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 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)

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 number.

The version of kernel installed on the remote host is prior to 5.10.173-154.642. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-028 advisory.

    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)

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

    netfilter: nft_tproxy: restrict to prerouting hook (CVE-2022-50001)

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

    drm: Fix potential null-ptr-deref due to drmm_mode_config_init() (CVE-2022-50556)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0458)

    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 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. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root.This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

    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)

    A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local     privilege escalation.

    The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free     vulnerability due a race condition with fixed files getting unregistered.

    We recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8. (CVE-2023-1872)

    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 iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in the SCSI     sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information.
    (CVE-2023-2162)

    In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the     drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually     an error pointer). (CVE-2023-22998)

    In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

    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)

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the 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)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux     kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)
