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

Description The issue arises from the function tzbsp pil verify sig() not strictly checking if the pointer to ELF and program headers and hash segment is within secure memory. It only verifies that the address is not in non-secure memory, which can lead to a situation where an address range overlapping both secure and non-secure regions could be considered valid, even though it could be modified by the non-secure side.

Recommendations For Android versions prior to 2018-04-05, update to a version with a security patch level of 2018-04-05 or later to resolve the issue.
