The impact is limited to availability, and no code execution is described. The affected driver and the exact version range are not published.
Affected
- Android kernel (affected component and version range not published)
Fixed in
- Pixel security patch level 2026-11-05 or later, according to the Pixel Update Bulletin for November 2026
- Unconfirmed: CVE-2026-58789 does not appear in the visible part of the bulletin's kernel table, so check Google's entry directly
Workaround
Unknown.
Exploitation
- No evidence of exploitation in the wild, public proof of concept or KEV listing was found.
- CISA SSVC: Exploitation none, Automatable yes, Technical Impact partial.
Our recommendation
- Verify that Pixel and Android devices are at security patch level 2026-11-05 or later and install the update.
- Check Samsung and other OEM bulletins for the same fix, as their coverage is unknown.
- Re-check NVD and the Pixel bulletin entry in a few days, since NVD analysis is still pending.
- Priority: moderate until the affected component is published.
