Google Android: Denial of service via integer overflow in UCE timer
Summary
A flaw in the StartTimer function of UcePublishManager.cpp allows an integer overflow during timer calculation. A remote attacker can trigger a process abort, which interrupts the affected service on the device. No privileges or user interaction are required, and the impact is limited to availability.
Affected
- Google Android, as listed in the CVE record (described as 'Android kernel'; the affected component appears to be a userspace service, not confirmed)
- Affected Android versions and builds: Unknown.
Fixed in
- Included in the Pixel Update Bulletin November 2026, patch level 2026-11-05 or later (target level; exact table entry for this CVE not confirmed)
- Fixed build numbers: Unknown.
Workaround
- Unknown. No vendor workaround or mitigation has been published.
Exploitation
- No known exploitation.
- Not listed in CISA KEV; no public proof of concept found.
- CISA SSVC: Automatable yes, technical impact partial.
Our recommendation
- Install the Android security update with patch level 2026-11-05 or later on all Pixel and Android devices via MDM.
- Check the security patch level on each device (Settings > About phone).
- Replace or isolate Pixel devices that no longer receive updates.
- Apply this as part of the normal monthly patch cycle.
