Overview
- Google’s November 2026 security bulletin lists 216 flaws, 23 rated Critical, with the first batch delivered as the 2026-11-01 patch level and the remainder in the 2026-11-05 patch level.
- The most severe flaw, CVE-2026-58868, affects Android 14 through 17 and is a heap buffer overflow in FrameDecoder.cpp that can cause an out-of-bounds write and allow remote code execution without user interaction.
- The 2026-11-05 patch set addresses kernel bugs and closed-source vendor components from MediaTek, Qualcomm, Arm, Imagination Technologies, and Unisoc, and MediaTek says it is not aware of active exploitation of its modem flaws.
- A related Critical issue, CVE-2026-58882, involves WAP Push/SMS handling and maps to public research called 'SMS of Death' that shows a crafted message can crash com.android.phone, drop calls and provoke crash loops on unpatched phones.
- No confirmed in-the-wild exploitation or CISA Known Exploited Vulnerabilities listings were reported in early November, but OEM and carrier rollout schedules vary and public proof-of-concepts mean unpatched devices remain at real risk of takeover or service loss.
