 (CVE-2023-29533)

 - Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash. (CVE-2023-29535)

 - An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker- controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.
 (CVE-2023-29536)

 - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
 (CVE-2023-29548)
