How do I determine if my device is updated to address these\nissues?**\n\nTo learn how to check a device's security patch level, read the\ninstructions on the\n[Google device update schedule](https://support.google.com/android/answer/7680439).\n\n- Security patch levels of 2024-07-01 or later address all issues associated with the 2024-07-01 security patch level.\n\nDevice manufacturers that include these updates should set the patch\nstring level to:\n\n- \\[ro.build.version.security_patch\\]:\\[2024-07-01\\]\n\nFor some devices on Android 10 or later, the Google Play system update\nwill have a date string that matches the 2024-07-01\nsecurity patch level.\nPlease see [this article](https://support.google.com/android/answer/7680439?hl=en) for more details on how\nto install security updates.\n\n\n**2. What do the entries in the *Type* column mean?**\n\nEntries in the *Type* column of the vulnerability details table\nreference 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\nEntries under the *References* column of the vulnerability details\ntable may contain a prefix identifying the organization to which the\nreference 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*\ncolumn mean?**\n\nIssues that are not publicly available have an \\* next to the corresponding\nreference ID. The update for that issue is generally contained in the latest\nbinary drivers for Pixel devices available from the\n[Google\nDeveloper site](https://developers.google.com/android/drivers).\n\n**5. Why are security vulnerabilities split between this bulletin\nand\ndevice / partner security bulletins, such as the\nPixel bulletin?**\n\nSecurity vulnerabilities that are documented in this security bulletin are\nrequired to declare the latest security patch level on Android\ndevices. Additional security vulnerabilities that are documented in the\ndevice / partner security bulletins are not required for\ndeclaring a security patch level. Android device and chipset manufacturers\nmay also publish security vulnerability details specific to their products,\nsuch as\n[Google](/security/bulletin/pixel),\n[Huawei](https://consumer.huawei.com/en/support/bulletin/),\n[LGE](https://lgsecurity.lge.com/security_updates_mobile.html),\n[Motorola](https://motorola-global-portal.custhelp.com/app/software-security-page/g_id/6806),\n[Nokia](https://www.nokia.com/phones/en_int/security-updates),\nor\n[Samsung](https://security.samsungmobile.com/securityUpdate.smsb).\n\nVersions\n--------\n\n| Version | Date | Notes |\n|---------|--------------|--------------------|\n| 1.0 | July 3, 2024 | Bulletin published |"]]
