Update: Baseband firmware trace analysis confirms buffer overflow, not just array index issue. Evidence from Jan 10 crash: - Explicit "!OVERFLOW!" marker in baseband trace (offset 0x00013365) - Watchdog reset: "rst wdog,6vdt_in_1" - Crash recovery: "gcb_crash_wakeup" - SDMState active at crash time Corrected flow: SDM transition → buffer overflow in baseband firmware → memory corruption → firmware deadlock → watchdog timeout → forced reboot Same trigger pattern on Jan 10, 11, 14. CWE-120 (Buffer Overflow) On Friday, January 16th, 2026 at 10:21 PM, Intergalactic Auditor via NANOG <nanog@lists.nanog.org> wrote:

Buffer overflow in Qualcomm X65 baseband

Issue: SDM state transition → unchecked array index → baseband deadlock → forced reboot Timeline: 9ms to error, 2.3s to crash Trigger: Potentially via 5G/satellite signal

Observed events: 2026-01-10, 01-11, 01-14 ~06:00 EST

Monitor for: - Clustered device crash reports in narrow time window - "No Service" complaints with normal network metrics - Baseband watchdog resets (rst wdog)
