常见问题和解答
这一部分解答了用户在阅读本公告后可能会提出的常见问题。
1. 如何确定我的设备是否已通过更新解决这些问题?
如果安全补丁级别是 2022-01-05 或更新,则意味着已解决 2022-01-05 以及之前的所有安全补丁级别涵盖的所有问题。如需了解如何查看设备的安全补丁程序级别,请参阅 Google 设备更新时间表中的说明。
2. “类型”列中的条目表示什么意思?
在漏洞详情表内,“类型”列中的条目是安全漏洞的分类。
缩写词 |

3. “参考编号”列中的条目表示什么意思?
在漏洞详情表内,“参考编号”列中的条目可能包含一个前缀,用于标识参考编号值所属的组织。
前缀 |
参考编号 |
A-
|
Android bug ID
|
QC-
|
Qualcomm 参考编号
|
M-
|
MediaTek 参考编号
|
N-
|
NVIDIA 参考编号
|
B-
|
Broadcom 参考编号
|
U-
|
UNISOC 参考编号
|
4. 在“参考编号”列中,Android Bug ID 旁边的 * 表示什么意思?
如果问题尚未公开发布,则在“参考编号”列中,相应 Android Bug ID 旁边会显示 *。Google Developers 网站上针对 Pixel 设备的最新二进制驱动程序中通常包含用于解决相应问题的更新。
5. 为什么要将安全漏洞拆分到本公告和 Android 安全公告中?
若要声明 Android 设备的最新安全补丁级别,必须修复 Android 安全公告中记录的安全漏洞。在声明安全补丁级别时,并不是必须要修复其他安全漏洞(如本公告中记录的漏洞)。

For Google devices, security patch levels of 2022-01-05 or later address all issues in this bulletin and all issues in the January 2022 Android Security Bulletin. To learn how to check a device's security patch level, see [Check and update your Android version](https://support.google.com/pixelphone/answer/4457705).\n\n\nAll supported Google devices will receive an update to the 2022-01-05 patch level. We encourage all customers to accept these updates to their devices.\n| **Note:** The Google device firmware images are available on the [Google Developer site](https://developers.google.com/android/images).\n\n**Announcements**\n-----------------\n\n- In addition to the security vulnerabilities described in the January 2022 Android Security Bulletin, Google devices also contain patches for the security vulnerabilities described below.\n\n**Security patches**\n--------------------\n\n\nVulnerabilities are grouped under the component that they affect. There is a description of the issue and a table with the CVE, associated references, [type of vulnerability](#type), [severity](/docs/security/overview/updates-resources#severity), and updated Android Open Source Project (AOSP) versions (where applicable). When available, we link the public change that addressed the issue to the bug ID, like the AOSP change list. When multiple changes relate to a single bug, additional references are linked to numbers following the bug ID.\n\n### **Pixel**\n\n| CVE | References | Type | Severity | Component |\n|----------------|-----------------------------|------|----------|------------------|\n| CVE-2021-39678 | A-171742549 [\\*](#asterisk) | EoP | High | Gboard |\n| CVE-2021-39679 | A-188745089 [\\*](#asterisk) | EoP | High | Display/graphics |\n| CVE-2021-39682 | A-201677538 [\\*](#asterisk) | EoP | High | Display/graphics |\n| CVE-2021-39683 | A-202003354 [\\*](#asterisk) | EoP | High | Titan M2 |\n| CVE-2021-39684 | A-203250788 [\\*](#asterisk) | EoP | High | Bootloader |\n| CVE-2021-40490 | A-199579676 [\\*](#asterisk) | EoP | High | Kernel |\n| CVE-2021-39680 | A-197965864 [\\*](#asterisk) | ID | High | Titan M2 |\n| CVE-2021-39681 | A-200251074 [\\*](#asterisk) | EoP | Moderate | Telephony |\n\n### **Qualcomm components**\n\n| CVE | References | | Severity | Component |\n|----------------|----------------------------------------------------------------------------------------------------------------------------------------|---|----------|-----------|\n| CVE-2021-30313 | A-178720043 [QC-CR#2878995](https://source.codeaurora.org/quic/le/kernel/msm-4.19/commit/?id=f181252f78036d1e5598fb618d2f3d2f47ba992c) | | Moderate | Kernel |\n\n### **Qualcomm closed-source components**\n\n| CVE | References | | Severity | Component |\n|----------------|-----------------------------|---|----------|-------------------------|\n| CVE-2021-30314 | A-193072178 [\\*](#asterisk) | | Moderate | Closed-source component |\n\n**Functional patches**\n----------------------\n\n\nFor details on the new bug fixes and functional patches included in this release, refer to the\n[Pixel Community forum](https://support.google.com/pixelphone/thread/143968432/google-pixel-update-january-2022).\n\n**Common questions and answers**\n--------------------------------\n\n\nThis section answers common questions that may occur after reading this bulletin.\n\n\n**1. How do I determine if my device is updated to address these issues?**\n\n\nSecurity patch levels of 2022-01-05 or later address all issues associated with the 2022-01-05\nsecurity patch level and all previous patch levels. To learn how to check a device's security\npatch level, read the instructions on the\n[Google\ndevice update schedule](https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices).\n\n\n**2. What do the entries in the *Type* column mean?**\n\n\nEntries in the *Type* column of the vulnerability details table reference the classification of the security vulnerability.\n\n| Abbreviation | Definition |\n|--------------|------------------------------|\n| RCE | Remote code execution |\n| EoP | Elevation of privilege |\n| ID | Information disclosure |\n| DoS | Denial of service |\n| N/A | Classification not available |\n\n\n**3. What do the entries in the *References* column mean?**\n\n\nEntries under the *References* column of the vulnerability details table may contain a prefix identifying the organization to which the reference value belongs.\n\n| Prefix | Reference |\n|--------|---------------------------|\n| A- | Android bug ID |\n| QC- | Qualcomm reference number |\n| M- | MediaTek reference number |\n| N- | NVIDIA reference number |\n| B- | Broadcom reference number |\n| U- | UNISOC reference number |\n\n\n**4. What does an \\* next to the Android bug ID in the *References* column mean?**\n\n\nIssues that are not publicly available have an \\* next to the Android bug ID in the\n*References* column. The update for that issue is generally contained in the latest\nbinary drivers for Pixel devices available from the\n[Google Developer site](https://developers.google.com/android/drivers).\n\n\n**5. Why are security vulnerabilities split between this bulletin and the Android Security\nBulletins?**\n\n\nSecurity vulnerabilities that are documented in the Android Security Bulletins are required to declare the latest security patch level on Android devices. Additional security vulnerabilities, such as those documented in this bulletin are not required for declaring a security patch level.\n\n**Versions**\n------------\n\n| Version | Date | Notes |\n|---------|-----------------|-------------------|\n| 1.0 | January 4, 2022 | Bulletin Released |"]]
