远程 18.04 LTS / 20.04 LTS 主机上安装的程序包受到 USN-6702-1 公告中提及的多个漏洞的影响。

  - 在 5.17之前的 Linux 内核中，drivers/phy/tegra/xusb.c 未正确处理 tegra_xusb_find_port_node 返回值。调用方在错误情况下预期为 NULL，但使用了错误指针。(CVE-2023-23000)

  - 在 Linux 内核 5.19 之前版本中，drivers/gpu/drm/arm/malidp_planes.c 会错译 get_sg_table 的返回值（预计在错误情况下会返回为 NULL，而实际上却是错误指针）。(CVE-2023-23004)

  - Linux 内核 netfilter: nf_tables 组件中存在一个释放后使用漏洞，攻击者可利用此漏洞以实现本地特权提升。nft_verdict_init() 函数允许在挂钩判定中将正值作为丢弃错误，因此，当 NF_DROP 发出类似于 NF_ACCEPT 的丢弃错误时，nf_hook_slow() 函数可造成双重释放漏洞。我们建议升级过去的提交 f342de4e2f33e0e39165d8639387aa6c19dff660。(CVE-2024-1086)

  - 在 Linux 内核的 scsi 设备驱动程序的 lpfc_unregister_fcf_rescan() 函数中发现争用条件。这可导致空指针取消引用问题，进而可能导致内核错误或拒绝服务问题。(CVE-2024-24855)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 Linux 内核 5.19 之前版本中，drivers/gpu/drm/arm/malidp_planes.c 会错译 get_sg_table 的返回值（预计在错误情况下会返回为 NULL，而实际上却是错误指针）。(CVE-2023-23004)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

远程主机上安装的 kernel-generic 版本低于 5.15.118/5.15.118_smp。因此，该应用程序受到 SSA:2023-172-02 公告中提及的漏洞影响。

  - KVM:VMX 内的 Linux 内核中存在回归漏洞，允许发起推测执行攻击。
    在 KVM (L0) 宣称会向 L1 提供 eIBRS 支持的背景下， L1 认为在运行 L2 之后便不需要使用 retpoline 或 IBPB，导致 L2 可以对 L1 执行 Spectre v2 攻击。在 L2 上拥有代码执行权的攻击者可以在主机的间接分支上执行代码。我们建议升级到内核 6.2 或过去的提交 2e7eab81425a (CVE-2022-2196)

  - 启用 SMT 后，某些 AMD 处理器可能在 SMT 模式切换后使用同级线程中的目标来推测性地执行指令，从而导致信息泄漏。 (CVE-2022-27672)

  - 在 Linux 内核中发现双重释放内存缺陷。Intel GVT-g 图形驱动程序触发 VGA 卡系统资源过载，从而导致 intel_gvt_dma_map_guest_page 函数失败。本地用户可以利用此问题造成系统崩溃。(CVE-2022-3707)

  - 在 Linux 内核流量控制 (TC) 子系统中发现缺陷。使用特定网络配置（使用 TC 操作镜像将出口数据包重定向到入口）时，本地非特权用户可在使用中的传输协议（TCP 或 SCTP）进行重新传输时触发 CPU 软锁定（ABBA 死锁），从而导致拒绝服务条件。(CVE-2022-4269)

  - 在 Linux 内核的 fs/nfs/nfs4file.c 内的 __nfs42_ssc_open() 中发现一个释放后使用漏洞。
    此缺陷允许攻击者进行远程拒绝 (CVE-2022-4379)

  - 在 6.2.7 及之前版本的 Linux 内核中，fs/ntfs3/inode.c 在重播日志前未验证 MFT 标记，因而包含无效的 kfree。(CVE-2022-48425)

  - Linux 内核 64 位版本上的 Copy_from_user 未实现 __uaccess_begin_nospec，这允许用户绕过 access_ok 检查并将内核指针传递到 copy_from_user()。这将允许攻击者泄漏信息。我们建议在提交 74e19ef0ff8061ef55957c3abd71614ef0f42f47 之后进行升级 (CVE-2023-0459)

  - Linux 内核中发现缺陷。由于其初始化函数中存在类型混淆，tun/tap 套接字将其套接字 UID 硬编码为 0。虽然此编码通常正确无误，但由于 tuntap 设备需要 CAP_NET_ADMIN，故而也会出错，例如仅具有该功能的非根用户。这会让 tun/tap 套接字在过滤/路由决策中遭到错误处理，从而可能绕过网络过滤器。(CVE-2023-1076)

  - 在 Linux 内核中，pick_next_rt_entity() 可能返回 BUG_ON 条件未检测到的类型混淆条目，因为混淆条目不是 NULL，而是 list_head。有缺陷的错误条件将导致具有列表标头的类型混淆的条目，随后其将被用作类型混淆的 sched_rt_entity，进而导致内存损坏。(CVE-2023-1077)

  - 在 Linux 内核的可靠数据报套接字 (RDS) 协议实现中发现一个缺陷。rds_rm_zerocopy_callback() 在造成类型混淆的列表标头上使用 list_entry()。本地用户可通过 rds_message_put() 触发此漏洞。类型混淆导致“struct rds_msg_zcopy_info *info”实际上指向可能由本地用户控制的其他内容。触发此漏洞的方式已由用户所知，该漏洞将导致越界访问和锁定损坏。(CVE-2023-1078)

  - Linux 内核中发现缺陷。当插入/断开宣称自己为 Asus 设备的恶意 USB 设备时，可能会在 asus_kbd_backlight_set 中触发释放后使用漏洞。与之前已知的 CVE-2023-25012 类似，但在 asus 设备中，LED 控制器可能会在设备断开连接时规划 work_struct，从而在 struct asus_kbd_leds *led 结构上触发释放后使用漏洞。恶意 USB 设备可能会利用此问题，通过受控数据造成内存损坏。
    (CVE-2023-1079)

  - 在用户分离 rc 设备的方式中，Linux 内核集成的红外接收器/收发器驱动程序中存在释放后使用缺陷。本地攻击者可利用此缺陷造成系统崩溃，或可能提升其在系统中的权限。(CVE-2023-1118)

  - Linux 内核流量控制索引过滤器 (tcindex) 中存在释放后使用漏洞，可造成权限升级。遍历数据包时可更新不完全哈希区域，这将在通过破坏的 tcf_ext 调用“tcf_exts_exec()”时造成释放后使用。本地攻击者用户可利用此漏洞将其权限提升至 root。此问题影响 Linux 内核：从 4.14 版至 git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2。(CVE-2023-1281)

  - 在 Linux 内核的 drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c 的 brcmf_get_assoc_ies 中发现越界读取问题。当 assoc_info->req_len 数据大于定义为 WL_EXTRA_BUF_MAX 的缓冲区大小时，可能会发生此问题，从而导致拒绝服务。(CVE-2023-1380)

  - 在 KVM 中发现缺陷。在 32 位系统上调用 KVM_GET_DEBUGREGS ioctl 时，kvm_debugregs 结构的某些未初始化部分可能会被复制到用户空间，从而导致信息泄漏。(CVE-2023-1513)

  - 在 Linux 内核中发现，btrfs 中 fs/btrfs/ctree.c 的 btrfs_search_slot 存在释放后使用缺陷。攻击者可利用此缺陷导致系统崩溃，并可能造成内核信息泄漏 (CVE-2023-1611)

  - 在 Linux 内核 Xircom 16 位 PCMCIA（PC 卡）以太网驱动程序中发现了一个释放后使用缺陷。本地用户可利用此缺陷导致系统崩溃或可能提升其在系统中的特权。
    (CVE-2023-1670)

  - Linux 内核流量控制索引过滤器 (tcindex) 中存在释放后使用漏洞，可造成特权提升。在删除底层结构期间发生完美哈希时，tcindex_delete 函数未正确停用过滤器，这随后可能会导致双重释放该结构。本地攻击者用户可利用此漏洞将其权限提升至 root。
    我们建议升级过去的提交 8c710f75256bb3cf05ac7b1672c82b92c43f3d28。(CVE-2023-1829)

  - 在 Hardware Monitoring Linux Kernel Driver (xgene-hwmon) 的 drivers/hwmon/xgene-hwmon.c 内的 xgene_hwmon_remove 中发现一个释放后使用缺陷。由于争用问题，此缺陷可能会让本地攻击者造成系统崩溃。此漏洞甚至可能导致内核信息泄漏问题。
    (CVE-2023-1855)

  - 在 Linux 内核的 9pfs 的 Xen 传输中，在 net/9p/trans_xen.c 的 xen_9pfs_front_removet 中发现一个释放后使用缺陷。此缺陷让本地攻击者可以因争用问题造成系统崩溃，进而可能导致内核信息泄露。(CVE-2023-1859)

  - 在 Linux 内核中 drivers\bluetooth\btsdio.c 的 btsdio_remove 中发现了一个释放后使用缺陷。在此缺陷中，若使用未完成的作业调用 btsdio_remove，可能会造成争用问题，从而在 hdev 设备上导致 UAF。(CVE-2023-1989)

  - 在 Linux 内核中 drivers/nfc/st-nci/ndlc.c 的 ndlc_remove 中发现了一个释放后使用缺陷。由于争用问题，此缺陷可能会让攻击者造成系统崩溃。(CVE-2023-1990)

  - 在 HCI 套接字实现中发现一个漏洞，出现此漏洞的原因是 Linux 内核的 net/bluetooth/hci_sock.c 中缺少功能检查。此缺陷让攻击者可以在未经授权的情况下执行管理命令，从而危害蓝牙通信的机密性、完整性和可用性。(CVE-2023-2002)

  - 在处理 RPL 协议期间，在 Linux 内核的网络子系统中发现一个缺陷。
    发生此问题的原因是未正确处理用户提供的数据，这可导致断言失败。这可能允许未经身份验证的远程攻击者在系统上创建拒绝服务情况。(CVE-2023-2156)

  - 在 Linux 内核的 SLIMpro I2C 设备驱动程序中发现越界写入漏洞。userspace data->block[0] 变量的上限未限定为 0-255 之间的数字，因而可将它用作 memcpy 的大小，这可能导致写入超出 dma_buffer 的末尾。有权限的本地用户可借此造成系统崩溃，或可能实现代码执行。(CVE-2023-2194)

  - Linux 内核性能事件系统中存在一个释放后使用漏洞，攻击者可利用此漏洞实现本地特权提升。perf_group_detach 函数在调用 add_event_to_groups() 前未检查事件同级组件的 attach_state，但是 remove_on_exec 可以在从其群组分离之前调用 list_del_event()，从而可以使用悬摆指针造成释放后使用漏洞。我们建议升级过去的提交 fd0815f632c24878e325821943edccc7fde947a2。(CVE-2023-2235)

  - ** REJECT ** 此 CVE ID 与 CVE-2023-31436 重复，已被其 CVE Numbering Authority 拒绝或撤回。(CVE-2023-2248)

  - 发现可能因为存在递归锁定情形而产生的拒绝服务问题，导致 Linux 内核 Device Mapper Multipathing 子组件中 drivers/md/dm-ioctl.c 的 table_clear 发生死锁。(CVE-2023-2269)

  - 在 Linux 内核 5.19 之前版本中，drivers/gpu/drm/arm/malidp_planes.c 会错译 get_sg_table 的返回值（预计在错误情况下会返回为 NULL，而实际上却是错误指针）。(CVE-2023-23004)

  - 在 6.1.9 及之前版本的 Linux 内核中，drivers/hid/hid-bigbenff.c 中的 bigben_remove 中通过构建的 USB 设备造成了释放后使用，这是因为 LED 控制器保持注册的时间过长。(CVE-2023-25012)

  - 在 6.1.13 版本之前的 Linux 内核中，由于设备重命名期间发生分配失败（用于在新位置注册 sysctl 表），net/mpls/af_mpls.c 中会存在双重释放漏洞。(CVE-2023-26545)

  - 在 Linux 内核 6.2.6 及其之前所有版本中，net/tls/tls_main.c 的 do_tls_getsockopt 缺少 lock_sock 调用，从而导致争用条件（造成释放后使用或空指针取消引用）。(CVE-2023-28466)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:1800-1 advisory.

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

  - A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4744)

  - 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)

  - 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 flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters. (CVE-2023-1076)

  - A flaw was 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 out of bounds access, and a lock corruption. (CVE-2023-1078)

  - In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

  - 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 data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while     loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system     to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

  - A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some     uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an     information leak. (CVE-2023-1513)

  - A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.
    This issue may allow a local attacker with user privilege to cause a denial of service. (CVE-2023-1582)

  - In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return     value (expects it to be NULL in the error case, whereas it is actually an error pointer). (CVE-2023-23004)

  - The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in drivers/hid/hid-bigbenff.c via a     crafted USB device because the LED controllers remain registered for too long. (CVE-2023-25012)

  - A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact     in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows     a local user to crash or potentially cause a denial of service. (CVE-2023-28327)

  - 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.
    This flaw allows a local user to crash the system or potentially cause a denial of service.

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-2023:1811-1 advisory.

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

  - A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier).

  - 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)

  - 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 flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability.

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-2023:1608-1 advisory.

  - A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is an unknown     function of the file mm/memory.c of the component Driver Handler. The manipulation leads to use after     free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue.
    The identifier of this vulnerability is VDB-211020. (CVE-2022-3523)

  - An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-36280)

  - A NULL pointer dereference vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c     in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a     local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).
    (CVE-2022-38096)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

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

    CVE-2022-2196

        A regression was discovered the KVM implementation for Intel CPUs,         affecting Spectre v2 mitigation for nested virtualisation.  When         KVM was used as the L0 hypervisor, an L2 guest could exploit this         to leak sensitive information from its L1 hypervisor.

    CVE-2022-3424

        Zheng Wang and Zhuorao Yang reported a flaw in the SGI GRU driver         which could lead to a use-after-free.  On systems where this driver         is used, a local user can explit this for denial of service (crash         or memory corruption) or possibly for privilege escalation.

        This driver is not enabled in Debian's official kernel         configurations.

    CVE-2022-3707

        Zheng Wang reported a flaw in the i915 graphics driver's         virtualisation (GVT-g) support that could lead to a double-free.
        On systems where this feature is used, a guest can exploit this         for denial of service (crash or memory corruption) or possibly for         privilege escalation.

    CVE-2022-4129

        Haowei Yan reported a race condition in the L2TP protocol         implementation which could lead to a null pointer dereference.  A         local user could exploit this for denial of service (crash).

    CVE-2022-4379

        Xingyuan Mo reported a flaw in the NFSv4.2 inter server to         server copy implementation which could lead to a use-after-free.

        This feature is not enabled in Debian's official kernel         configurations.

    CVE-2023-0045

        Rodrigo Branco and Rafael Correa De Ysasi reported that when a         user-space task told the kernel to enable Spectre v2 mitigation         for it, the mitigation was not enabled until the task was next         rescheduled.  This might be exploitable by a local or remote         attacker to leak sensitive information from such an application.

    CVE-2023-0458

        Jordy Zimmer and Alexandra Sandulescu found that getrlimit() and         related system calls were vulnerable to speculative execution         attacks such as Spectre v1.  A local user could explot this to         leak sensitive information from the kernel.

    CVE-2023-0459

        Jordy Zimmer and Alexandra Sandulescu found a regression in         Spectre v1 mitigation in the user-copy functions for the amd64         (64-bit PC) architecture.  Where the CPUs do not implement SMAP or         it is disabled, a local user could exploit this to leak sensitive         information from the kernel.  Other architectures may also be         affected.

    CVE-2023-0461

        slipper reported a flaw in the kernel's support for ULPs (Upper         Layer Protocols) on top of TCP that can lead to a double-free when         using kernel TLS sockets.  A local user can exploit this for         denial of service (crash or memory corruption) or possibly for         privilege escalation.

        Kernel TLS is not enabled in Debian's official kernel         configurations.

    CVE-2023-1073

        Pietro Borrello reported a type confusion flaw in the HID (Human         Interface Device) subsystem.  An attacker able to insert and         remove USB devices might be able to use this to cause a denial of         service (crash or memory corruption) or possibly to run arbitrary         code in the kernel.

    CVE-2023-1074

        Pietro Borrello reported a type confusion flaw in the SCTP         protocol implementation which can lead to a memory leak.  A local         user could exploit this to cause a denial of service (resource         exhaustion).

    CVE-2023-1076

        Pietro Borrello reported a type confusion flaw in the TUN/TAP         network driver, which results in all TUN/TAP sockets being marked         as belonging to user ID 0 (root).  This may allow local users to         evade local firewall rules based on user ID.

    CVE-2023-1077

        Pietro Borrello reported a type confusion flaw in the task         scheduler.  A local user might be able to exploit this to cause a         denial of service (crash or memory corruption) or possibly for         privilege escalation.

    CVE-2023-1078

        Pietro Borrello reported a type confusion flaw in the RDS protocol         implementation.  A local user could exploit this to cause a denial         of service (crash or memory corruption) or possibly for privilege         escalation.

    CVE-2023-1079

        Pietro Borrello reported a race condition in the hid-asus HID         driver which could lead to a use-after-free.  An attacker able to         insert and remove USB devices can use this to cause a denial of         service (crash or memory corruption) or possibly to run arbitrary         code in the kernel.

    CVE-2023-1118

        Duoming Zhou reported a race condition in the ene_ir remote         control driver that can lead to a use-after-free if the driver         is unbound.  It is not clear what the security impact of this is.
