Name of the Vulnerable Software and Affected Versions: Android versions prior to security patch level 2018-04-05

Description: The issue is related to the Qualcomm Trusted Execution Environment component in the Android operating system, which is associated with incorrect ECDSA cryptographic signature verification. This can allow a remote attacker to impact the confidentiality, integrity, and availability of protected information. In certain corner cases, ECDSA signature verification can fail.

Recommendations: For Android versions prior to security patch level 2018-04-05, update to a version with a security patch level of 2018-04-05 or later to resolve the issue. As a temporary workaround, consider restricting the use of ECDSA signature verification in sensitive operations until a patch is available.
