The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - io_uring use work_flags to determine which identity need to grab from the calling process to make sure it     is consistent with the calling process when executing IORING_OP. Some operations are missing some types,     which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading     the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859 (CVE-2022-2327)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the linux package has been released.

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。

  - io_uring 在执行 IORING_OP 时使用 work_flags 来确定需要从调用进程获取哪个标识以确保其与调用进程一致。某些操作缺少某些类型这可导致引用计数不正确进而导致双重释放。建议升级提交后的 内核 df3f3bb5059d20ef094d6b2f0256c4bf4127a859 (CVE-2022-2327)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - io_uring は work_flags を使用して、呼び出しプロセスからどの ID を取得する必要があるかを決定し、IORING_OP の実行時に呼び出しプロセスと一致するようにします。一部の操作に一部のタイプがないため、間違った参照カウントが発生し、二重解放が発生する可能性があります。カーネル過去のコミット df3f3bb5059d20ef094d6b2f0256c4bf4127a859 をアップグレードすることを推奨しますCVE-2022-2327

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - io_uring 使用 work_flags 判斷執行 IORING_OP 時需要從呼叫處理程序抓取的身分以確保其與呼叫處理程序一致。某些作業遺漏某些類型進而導致不正確的參照計數進而導致重複釋放。我們建議升級核心以解決提交 df3f3bb5059d20ef094d6b2f0256c4bf4127a859 (CVE-2022-2327)

請注意，Nessus 依賴供應商報告的套件存在。

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - In rcu_cblist_dequeue of rcu_segcblist.c, there is a possible use-after-free due to improper locking. This     could lead to local escalation of privilege in the kernel with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-222091980References: Upstream kernel (CVE-2022-20153)

  - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel     (CVE-2022-20368)

  - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input     validation. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-223375145References: Upstream kernel (CVE-2022-20369)

  - io_uring use work_flags to determine which identity need to grab from the calling process to make sure it     is consistent with the calling process when executing IORING_OP. Some operations are missing some types,     which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading     the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859 (CVE-2022-2327)

  - The Linux kernel was found vulnerable out of bounds memory access in the     drivers/video/fbdev/sm712fb.c:smtcfb_read() function. The vulnerability could result in local attackers     being able to crash the kernel. (CVE-2022-2380)

  - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to     restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently     allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass     verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and     unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for     peripherals that do not verify firmware updates. We recommend upgrading past commit     4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller     driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input     data. This flaw allows a local user to crash the system. (CVE-2022-2873)

  - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet     Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
    (CVE-2022-2964)

  - The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This     allows Xen PV guest OS users to cause a denial of service or gain privileges. (CVE-2022-36123)

  - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

  - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679) (CVE-2022-2586)

  - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation     (CVE-2022-2588)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
