macOS AppleGVA Memory Handling
On Intel macOS, HEVC video decoding is performed in the AppleGVA module. Using fuzzing, researchers identified multiple issues in this decoder. The issues range from out-of-bounds writes, out-of-bounds reads and, in one case, free() on an invalid address. All of the issues were reproduced on macOS Ventura 13.6 running on a 2018 Mac mini (Intel based).
