Technical details
The vulnerability exists in the IMS stack component of the Exynos modem firmware, where malformed or specially crafted SDP payloads are not properly validated, leading to a denial of service condition. An attacker with network access to trigger SDP message processing (such as via incoming call or data session setup) can cause the modem to become unresponsive. A firmware update is required to resolve this issue.
