Severity by source
AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Local unprivileged app reaches the codec (AV:L/PR:N/UI:N); an OOB read yields memory disclosure (C:H) and at most a crash (A:L), with no integrity impact (I:N).

In Vp9DecEndOfStream of vp9hwd_output.cc, there is a possible out-of-bounds read due to an incorrect bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
Articles & Coverage 1
AnalysisAI
An out-of-bounds read in the Android hardware VP9 decode path (Vp9DecEndOfStream in vp9hwd_output.cc) permits a locally installed app that can feed a crafted VP9 bitstream to the platform decoder to read memory beyond the intended buffer, leaking process data. Exploitation requires a local foothold (AV:L) - an app already running on the device - but no additional privileges (PR:N) and no user interaction (UI:N); the flaw is confined to devices using Google/Tensor's hardware VP9 decode implementation and is not remotely exploitable. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires the attacker to already execute local code on the affected Pixel/Android device (AV:L) - typically an installed app - that can hand a crafted VP9 bitstream to the platform's hardware VP9 decoder path (vp9hwd_output.cc Vp9DecEndOfStream). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals point to a low real-world priority despite the 8.4 (High) vendor CVSS. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary action is to apply Google's September 2026 Pixel/Android security bulletin update (https://source.android.com/docs/security/bulletin/pixel/2026/2026-09-01), which is where the fix for CVE-2026-58699 is published; the supplied data does not include an exact patch build or version string, so reference the bulletin's build list for the confirmed patched level (patch status: "Patch available per vendor advisory"). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify which managed Android devices use Google/Tensor hardware VP9 decode (primarily Pixel and other Tensor-based models) via your EMM/MDM inventory, and confirm that Google Play Protect is enabled and that unknown-source/sideloading is blocked on those fleets. …
