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.

Microsoft Patches Record 974 Flaws, Including Two Exploited Windows Zero-Days
Microsoft's September Patch Tuesday fixed a record 974 flaws, including two Windows privilege-escalation zero-days actively exploited and added to CISA's KEV catalog.
Microsoft's September 2026 Patch Tuesday addressed a record 974 vulnerabilities (999 including 25 non-Microsoft CVEs), with over 110 rated critical; 723 affect Windows and 111 affect Office. Two Windows privilege-escalation zero-days are actively exploited: CVE-2026-85880, an ALPC heap-based buffer overflow, and CVE-2026-81963, an improper link resolution flaw in the Windows Update Stack, both allowing attackers to gain SYSTEM privileges. CISA added both flaws to its KEV catalog, giving federal civilian agencies until September 22, 2026 to apply fixes. Volexity, Proofpoint, MSTIC, and independent researchers were credited with the reports; notable additional fixes include network-reachable RCEs in Exchange, SharePoint, SQL Server, Remote Desktop Services, DNS, and DHCP.
