Memory corruption via out-of-bounds SIM buffer access
Published Nov 30, 2023 · Updated Aug 2, 2024
Out-of-bounds buffer access in ASR1803 and ASR1806 modem SIM management allows attackers to corrupt memory during USIM Phase 2 initialization. ASR identifies the affected subsystem and initialization phase but does not disclose the buffer, input, or incorrect operation involved. The published assessment requires adjacent access, high privileges, and user interaction; the concrete post-corruption outcome remains undisclosed.
