Android Update Fixes Three Critical RCE Flaws and Additional Component Vulnerabilities

Google’s November 2026 Android Security Bulletin addresses three critical remote code execution vulnerabilities—CVE-2026-58868, CVE-2026-58876, and CVE-2026-58936—affecting Android 14, 15, 16, 16 QPR2, and 17. Google states that the most severe Framework and System vulnerabilities require neither user interaction nor additional execution privileges, although published details do not establish identical exploitation conditions for all three flaws. The bulletin does not identify these vulnerabilities as actively exploited.

The 2026-11-01 security patch level covers all three critical RCE flaws, while 2026-11-05 additionally addresses kernel and other component vulnerabilities, including critical privilege-escalation flaws. The broader fixes cover media processing, Bluetooth, pKVM, HID, MediaTek modem components, and a Qualcomm closed-source component, with reported impacts also including information disclosure and denial of service. gmCSIRT urges organizations to apply patch level 2026-11-05 or later where available and verify managed-device compliance; device manufacturers control update distribution.
