CVE-2022-48455
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 wifi service, there is a possible out of bounds write due to a missing bounds check. This could lead to local denial of service with no additional execution privileges needed
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 · moderate confidenceIn the wifi service component, an out-of-bounds write vulnerability exists due to a missing bounds check. This allows a local attacker to trigger the vulnerability without requiring elevated privileges, potentially causing a denial of service through memory corruption.

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 versionCheck the Android OS version on the device via Settings > About Phone > Android version, or run the command `getprop ro.build.version.release` in a terminalAffected if The reported Android version is 11.0, 12.0, or 13.0 (exact match to affected versions)
-
Verify WiFi service is accessibleConfirm that WiFi functionality is enabled on the device. Check if the WiFi service daemon process is running using `ps -A | grep wifi` or observe WiFi toggle status in SettingsAffected if WiFi is enabled and the wifi service component is active on an affected Android version
-
Monitor for WiFi service crashesReview system logs for wifi service crashes or anomalies using `logcat -d | grep -i wifi` or check for frequent WiFi-related force closes in Settings > Apps > WiFi serviceAffected if Unexpected crashes, ANRs (Application Not Responding), or memory corruption symptoms related to the wifi service occur on an affected version
The environment is likely affected if the device runs Android 11.0, 12.0, or 13.0 and the WiFi service component is active, as this is where the out-of-bounds write in the wifi service can be triggered without elevated privileges.

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 available security patches for the wifi service component; until then, monitor for unexpected wifi service crashes and restrict untrusted local applications where possible.
