Tenable has extracted the preceding description block directly from the SUSE 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 5.15.93-55.139. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2024-037 advisory.

    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

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

    cpufreq: governor: Use kobject release() method to free dbs_data (CVE-2022-49513)

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

    ovl: Use buf flexible array for memcpy() destination (CVE-2022-49743)

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

    perf/x86/amd: fix potential integer overflow on shift of a int (CVE-2022-49748)

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

    device property: fix of node refcount leak in fwnode_graph_get_next_endpoint() (CVE-2022-49752)

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

    dmaengine: Fix double increment of client_count in dma_chan_get() (CVE-2022-49753)

    A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with     capabilities was found in the Linux kernel's OverlayFS subsystem in how a user copies a capable file from     a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges     on the system. (CVE-2023-0386)

    A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

    A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the     Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel     information leak problem. (CVE-2023-1652)

    In the Linux kernel 6.0.8, there is a use-after-free in inode_cgwb_move_to_attached in fs/fs-writeback.c,     related to __list_del_entry_valid. (CVE-2023-26605)

    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)

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 5.4.231-137.341. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-042 advisory.

    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

    In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

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

    udf: Fix preallocation discarding at indirect extent boundary (CVE-2022-48946)

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

    igb: Initialize mailbox message for VF reset (CVE-2022-48949)

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

    perf/x86/amd: fix potential integer overflow on shift of a int (CVE-2022-49748)

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

    dmaengine: Fix double increment of client_count in dma_chan_get() (CVE-2022-49753)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

    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-2023-0459)

    There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.

    There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.

    When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket.
    The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is     created from the listener, the context is inherited and vulnerable.

    The setsockopt TCP_ULP operation does not require any privilege.

    We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

    A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

    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)
