https://notcve.org/view.php?id=CVE-2021-44078
An issue was discovered in split_region in uc.c in Unicorn Engine before 2.0.0-rc5. It allows local attackers to escape the sandbox. An attacker must first obtain the ability to execute crafted code in the target sandbox in order to exploit this vulnerability. The specific flaw exists within the virtual memory manager. The issue results from the faulty comparison of GVA and GPA while calling uc_mem_map_ptr to free part of a claimed memory block. • https://gist.github.com/jwang-a/cb4b6e9551457aa299066076b836a2cd https://github.com/jwang-a/CTF/blob/master/MyChallenges/Pwn/Unicorns_Aisle/UnicornsAisle.pdf https://github.com/unicorn-engine/unicorn/commit/c733bbada356b0373fa8aa72c044574bb855fd24 https://github.com/unicorn-engine/unicorn/compare/2.0.0-rc4...2.0.0-rc5 https://www.unicorn-engine.org/changelog • CWE-697: Incorrect Comparison •
