AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
WC-Radio is a baseband-style component reached over radio proximity (AV:A), exploitation needs a precisely crafted frame (AC:H), but no auth or interaction is required and impact is total.
Primary rating from NVD.

Lifecycle Timeline
4DescriptionNVD
In WC-Radio, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Remote code execution in the WC-Radio component on Google Android (Pixel) devices allows network-adjacent attackers to corrupt memory via an out-of-bounds write with no authentication or user interaction. The flaw carries a CVSS 9.8 rating and is addressed in the Pixel security bulletin dated 2026-06-01; no public exploit identified at time of analysis and EPSS is low at 0.15%.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The vulnerable WC-Radio component must be present and active on the target Android device (Pixel builds prior to the 2026-06-01 patch level, and equivalent OEM builds that ship WC-Radio); the device's radio interface that WC-Radio services must be powered on and reachable by the attacker's transmitter. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) and total technical impact in SSVC indicate maximum theoretical severity, but real-world signals soften the picture: CISA SSVC marks Exploitation as 'none' and Automatable as 'no', EPSS is only 0.15% (5th percentile), and no public exploit is identified. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker within radio range of a vulnerable Android device crafts a malformed WC-Radio protocol frame that exceeds expected buffer length, triggering the out-of-bounds write inside the radio component and corrupting adjacent memory to redirect execution into attacker-supplied shellcode. Because no user interaction or authentication is required, the victim simply has the radio enabled; successful exploitation yields code execution in a privileged Android process. … |
| Remediation | Apply the Pixel security patch level dated 2026-06-01 or later as published in the Google bulletin (https://source.android.com/docs/security/bulletin/pixel/2026/2026-06-01); the exact fix build for Pixel devices is enumerated in that advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
