Google Patches Pixel Modem Zero-Day Exploited in Targeted Attacks
Google patched Pixel modem zero-day CVE-2026-58704 (CVSS 8.0), exploited in limited targeted attacks, enabling adjacent privilege escalation without user interaction.
Google's September 2026 Pixel security update fixes CVE-2026-58704, a CVSS 8.0 permission bypass caused by a logic error in the cellular modem, allowing remote (proximal/adjacent) elevation of privilege with no user interaction or additional privileges. Google confirms indications of limited, targeted exploitation in the wild but provides no attribution, target count, or attack objectives. The modem location is significant because it operates below much of the Android application security model. The bulletin also patches multiple critical RCE flaws in IMS, libpixelimsmedia, VPU, modem, telephone and BigOcean components, with the 2026-09-05 patch level protecting devices.

Google Pixel owners urged to patch actively exploited modem flaw
Google's September 2026 Pixel bulletin fixes 110 vulnerabilities, including CVE-2026-58704, a modem permission bypass under limited targeted exploitation enabling remote privilege escalation.
Google released the September 2026 Pixel Update Bulletin addressing 110 vulnerabilities, including CVE-2026-58704, a high-severity logic error in the cellular modem that allows remote escalation of privilege with no additional execution privileges or user interaction required. Google says there are indications the flaw may be under limited, targeted exploitation; attackers need adjacent network access and some existing foothold on the device, which the bulletin does not explain how to obtain. The fix ships at the 2026-09-05 patch level and appears only in the Pixel-specific bulletin, so other Android vendors do not receive this specific fix.

Pixel Modem Zero-Day Exploited in Targeted Attacks
Google patched Pixel modem zero-day CVE-2026-58704, a zero-click permission bypass enabling remote privilege escalation, exploited in targeted attacks.
CVE-2026-58704 is a high-severity logic error in the Pixel cellular modem allowing remote (proximal/adjacent) escalation of privilege with no user interaction or additional execution privileges. Google reports limited, targeted exploitation but has not attributed it; the zero-click modem nature suggests commercial spyware or state-sponsored actors. The September Pixel update also fixes more than 100 other Pixel-specific vulnerabilities, nearly 50 of them critical, enabling RCE or privilege escalation.

Google Patches Pixel Modem Flaw Amid Signs of Limited Targeted Exploitation
Google's September Pixel update patches CVE-2026-58704, a high-severity cellular modem privilege escalation flaw showing signs of limited targeted exploitation.
Google disclosed CVE-2026-58704 (CVSS 8.0), a privilege escalation flaw in the Pixel Cellular Modem caused by a logic error permitting proximal/adjacent privilege escalation with no user interaction or extra privileges needed. Google acknowledged indications the flaw may be under limited, targeted exploitation but did not identify the threat actor. The September 2026 Pixel update fixes 109 additional flaws, including 46 critical-severity issues in components such as BigOcean, Bootloader, IMS, and Trusted Execution Environment, plus two high-severity kernel privilege escalation bugs (CVE-2026-56914, CVE-2026-58773). Security patch level 2026-09-05 or later resolves all identified flaws.

Android 0-day Vulnerability on Google Pixel Devices Actively Exploited in Attacks
Google patched CVE-2026-58704, an actively exploited Android zero-day allowing proximal privilege escalation via the Pixel cellular modem, urging the 2026-09-05 patch.
Google confirmed CVE-2026-58704, a high-severity elevation-of-privilege flaw in the Pixel cellular modem, is being exploited in limited, targeted attacks and shipped emergency fixes in the September 2026 Pixel Update Bulletin. The low-complexity bug requires no user interaction and enables proximal/adjacent privilege escalation with no additional execution privileges, phrasing Google has historically used for spyware-vendor and state-aligned zero-days. The Pixel bulletin patches 110 flaws including 12 critical RCEs, while the broader September Android update addressed roughly 180 vulnerabilities, including Wi-Fi memory-corruption bug CVE-2026-28662.

Google Pixel phones pwned in zero-click attacksnew
CISA added actively exploited zero-click Pixel modem flaw CVE-2026-58704 to its KEV catalog, giving federal agencies three days to patch.
Google disclosed CVE-2026-58704, a high-severity improper authorization flaw in Pixel phones' cellular modems that bypasses permission checks and escalates privileges with no user interaction, noting limited, targeted exploitation. CISA added it to the Known Exploited Vulnerabilities Catalog with a September 19 deadline for federal agencies. Such zero-click modem bugs are a frequent vector for commercial spyware. The Register also notes two recently KEV-listed Chromium V8 flaws, CVE-2026-85046 and CVE-2026-87491, which Proofpoint says four espionage groups chained in intrusions.

Google says some Pixel phone owners were hacked in zero-day attacks
Google patched CVE-2026-58704, a zero-click Pixel modem privilege-escalation zero-day exploited in limited, targeted attacks.
Google disclosed that a vulnerability in Pixel smartphones' modem software, tracked as CVE-2026-58704, was exploited in limited and targeted cyberattacks and has now been patched. Exploitation could allow an attacker to escape the modem sandbox and escalate privileges to access broader phone data. The bug can be exploited silently with zero user interaction. Google did not attribute the activity, though such modem bugs are commonly abused by surveillance vendors selling spyware to governments.

CISA Warns Water Utilities: Find Your Exposed PLCs Before Attackers Do
CISA urged water utilities to secure internet-exposed PLCs after July 2026 attacks compromised over 100 US water and wastewater systems, suspected Iran-linked.
CISA's exposure-reduction guidance, published August 21, follows July 2026 attacks in which threat actors remotely accessed PLCs connected directly through cellular modems, changed device IP addresses and passwords, and in some cases disabled alarms and shutdown processes without notifying operators. Iran is the suspected actor, though officials stopped short of formal attribution. CISA recommends routing remote access through centrally managed secure gateways, phishing-resistant MFA, unique credentials, and external scanning of industrial protocols such as Modbus, EtherNet/IP, DNP3, BACnet and OPC UA.
