CVE-2022-42755
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 wlan driver, there is a possible missing bounds check, This could lead to local denial of service in wlan services.
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 confidenceA missing bounds check in the wlan driver allows a local attacker to trigger an out-of-bounds memory access, causing the wlan services to crash and resulting in denial of service.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 device or system settings for the Android OS version. This is typically found under Settings > About Phone > Android versionAffected if The installed Android version is 10.0, 11.0, or 12.0
-
Verify wlan functionality is presentConfirm that Wi-Fi or wireless LAN (wlan) functionality is enabled and available on the device. Check system settings or use diagnostic tools to verify wlan driver is loadedAffected if Wlan is enabled and the wlan driver is active on the system
-
Confirm wlan driver is in useCheck if the wlan driver module is loaded and actively managing wireless communications. This can be verified through system diagnostics or kernel module listingsAffected if The wlan driver is loaded and handling wireless communications
A system is affected if it runs Android 10.0, 11.0, or 12.0 with an active wlan driver, as the missing bounds check in the driver can be exploited for denial of service.

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.
dbcve · scopedApply vendor-provided patches for the wlan driver firmware. Until patched, restrict local access to trusted users only to reduce the attack surface.
Latest Android security patch level (check with OEM for specific version containing Unisoc wlan driver fix)
- Check with your device manufacturer (OEM) for the latest Android security patch level that includes the fix for this Unisoc wlan driver vulnerability
- Ensure the device is running the most recent Android security update available from your OEM
- If your device is no longer receiving monthly security updates from the manufacturer, consider upgrading to a newer device that receives active security support
- Verify the installed patch level by going to Settings > About Phone > Android version and checking that the Security patch level is current
