  - A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588) (CVE-2023-34319)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. (CVE-2023-3610)

  - An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

  - A use-after-free flaw was found in nfc_llcp_find_local in net/nfc/llcp_core.c in NFC in the Linux kernel.
    This flaw allows a local user with special privileges to impact a kernel information leak issue.

This     flaw allows a local user to crash the system, causing a denial of service condition. (CVE-2023-4133)

  - A use-after-free flaw was found in the Linux kernel's Netfilter functionality when adding a rule with     NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
    (CVE-2023-4147)

  - A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 (tun: tun_chr_open(): correctly initialize socket uid), - 66b2c338adce (tap: tap_open():
    correctly initialize socket uid), pass inode->i_uid to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

  - A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation     of the file name reconstruction function, which is responsible for reading file name entries from a     directory index and merging file name parts belonging to one file into a single long file name. Since the     file name characters are copied into a stack variable, a local privileged attacker could use this flaw to     overflow the kernel stack. (CVE-2023-4273)

  - A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem. (CVE-2023-4387)

  - A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during cleanup.
    (CVE-2023-4459)

  - A memory leak flaw was found in nft_set_catchall_flush in net/netfilter/nf_tables_api.c in the Linux     Kernel. This issue may allow a local attacker to cause a double-deactivations of catchall elements, which     results in a memory leak. (CVE-2023-4569)

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

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3964-1 advisory.

  - The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper     locking when performing operations on an object. An attacker can leverage this in conjunction with other     vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel.
    (CVE-2023-2007)

  - A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588)

  - The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a     way such that not all of the headers would come in one piece. Unfortunately the logic introduced there     didn't account for the extreme case of the entire packet being split into as many pieces as permitted by     the protocol, yet still being smaller than the area that's specially dealt with to keep all (possible)     headers together. Such an unusual packet would therefore trigger a buffer overrun in the driver.
    (CVE-2023-34319)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. (CVE-2023-3610)

  - An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

  - A use-after-free flaw was found in nfc_llcp_find_local in net/nfc/llcp_core.c in NFC in the Linux kernel.
    This flaw allows a local user with special privileges to impact a kernel information leak issue.
    (CVE-2023-3863)

  - A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue. (CVE-2023-4128)

  - A use-after-free vulnerability was found in the cxgb4 driver in the Linux kernel. The bug occurs when the     cxgb4 device is detaching due to a possible rearming of the flower_stats_timer from the work queue. This     flaw allows a local user to crash the system, causing a denial of service condition. (CVE-2023-4133)

  - A use-after-free flaw was found in the Linux kernel's Netfilter functionality when adding a rule with     NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
    (CVE-2023-4147)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    CVE-2022-4269

        William Zhao discovered that a flaw in the Traffic Control (TC)         subsystem when using a specific networking configuration         (redirecting egress packets to ingress using TC action mirred),         may allow a local unprivileged user to cause a denial of service         (triggering a CPU soft lockup).

    CVE-2022-39189

        Jann Horn discovered that TLB flush operations are mishandled in         the KVM subsystem in certain KVM_VCPU_PREEMPTED situations, which         may allow an unprivileged guest user to compromise the guest         kernel.

    CVE-2023-1206

        It was discovered that the networking stack permits attackers to         force hash collisions in the IPv6 connection lookup table, which         may result in denial of service (significant increase in the cost         of lookups, increased CPU utilization).

    CVE-2023-1380

        Jisoo Jang reported a heap out-of-bounds read in the brcmfmac         Wi-Fi driver. On systems using this driver, a local user could         exploit this to read sensitive information or to cause a denial of         service.

    CVE-2023-2002

        Ruiahn Li reported an incorrect permissions check in the Bluetooth         subsystem. A local user could exploit this to reconfigure local         Bluetooth interfaces, resulting in information leaks, spoofing, or         denial of service (loss of connection).

    CVE-2023-2007

        Lucas Leong and Reno Robert discovered a         time-of-check-to-time-of-use flaw in the dpt_i2o SCSI controller         driver. A local user with access to a SCSI device using this         driver could exploit this for privilege escalation.

        This flaw has been mitigated by removing support for the I2OUSRCMD         operation.

    CVE-2023-2124
