CVE-2022-20099
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn aee daemon, 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. Patch ID: ALPS06296442; Issue ID: ALPS06296442.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an out-of-bounds write vulnerability in the aee (Android Error Engineer) daemon caused by improper input validation. The flaw could allow a local attacker to escalate privileges to System level without any user interaction. The vulnerability is addressed by vendor patch ALPS06296442.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Android versionRun 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if The version is exactly 11.0 or 12.0 (not 11.0.x or 12.0.x variants)
-
Locate the aee daemon binaryCheck for /vendor/bin/aee or /system/bin/aee existence via 'ls -la /vendor/bin/aee' or 'ls -la /system/bin/aee'Affected if The aee binary exists on the device - the vulnerability only applies where this daemon is present
-
Verify aee daemon is runningRun 'ps -A | grep aee' to check if the aee process is activeAffected if The aee daemon process is running - the out-of-bounds write occurs in the active daemon
-
Check security patch levelRun 'getprop ro.build.version.security_patch' to see the installed security patch dateAffected if The security patch level is earlier than the vendor patch ALPS06296442 (patch date not specified in provided data, so compare against known patch release dates for this CVE)
The device is affected if it runs Android version 11.0 or 12.0, contains the aee daemon binary, and lacks the vendor patch ALPS06296442.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch ALPS06296442 to address the input validation vulnerability in the aee daemon. As a system-level daemon, ensure the fix does not disrupt core error reporting functionality.
