Security readout for executives and security teams
Plain-English summary
CVE-2022-20350 is an Android flaw that could let a local attacker cause notification access to be granted to the wrong app. That access can expose sensitive notification content. The issue affects Android 10, 11, 12, and 12L, and was addressed in Android’s August 2022 security bulletin.
Executive priority
Treat as a moderate mobile privacy risk. It is not cited as actively exploited, but notification access can expose sensitive business messages, MFA prompts, and personal data on unpatched Android devices.
Technical view
The source describes improper input validation in NotificationAccessConfirmationActivity.onCreate. The vulnerability can result in local information disclosure with no required privileges or user interaction under CVSS v3.1, although the narrative also says user execution privileges are needed. Confidentiality impact is rated high; integrity and availability are not impacted.
Likely exposure
Exposure is most likely on Android 10 through 12L devices missing the August 2022 Android security update or equivalent OEM patch level.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The CVSS vector is local, low complexity, no privileges, no user interaction, with high confidentiality impact.
Researcher notes
Evidence is limited to CVE metadata and the Android bulletin reference. The listed CWE-125 does not neatly match the described notification permission confusion, so validation should rely on Android patch status and advisory details rather than CWE interpretation alone.
Mitigation direction
- Apply Android August 2022 security updates or later OEM security patches.
- Prioritize Android 10, 11, 12, and 12L devices below the fixed patch level.
- Check vendor or OEM guidance for device-specific patch availability.
- Restrict notification access to trusted apps through device policy where possible.
- Remove unknown or unnecessary apps with notification listener access.
Validation and detection
- Inventory Android OS versions and security patch levels across managed devices.
- Confirm affected devices report August 2022 security patch level or later.
- Review notification access settings for unexpected or untrusted apps.
- Verify OEM release notes map the device build to the Android August 2022 bulletin.
- Document exceptions where unsupported devices cannot receive vendor fixes.
