This vulnerability occurs because of computation that reads data that is past the end of the target buffer; the computation is part of Adobe Texture Format (ATF) decoding of lossy compressed ETC2 format. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.
