Samsung · Samsung Galaxy S10 · CVE-2020-8860
**Name of the Vulnerable Software and Affected Versions**
Samsung Galaxy S10 Firmware versions G973FXXS3ASJA, O(8.x), P(9.0), Q(10.0)
**Description**
This issue allows remote attackers to execute arbitrary code on affected devices. The exploitation requires user interaction, specifically answering a phone call. The flaw exists within the Call Control Setup messages due to the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this to execute code in the context of the baseband processor.
**Recommendations**
For Samsung Galaxy S10 Firmware version G973FXXS3ASJA, update to a version that fixes the issue with proper validation of user-supplied data length.
For Samsung Galaxy S10 Firmware versions O(8.x), P(9.0), Q(10.0), ensure that all Call Control Setup messages are properly validated to prevent stack-based buffer overflow.
As a temporary workaround, consider restricting or disabling the handling of Call Control Setup messages until a patch is available.
