CVE-2024-43102

Concurrent removals of certain anonymous shared memory mappings by using the UMTXSHMDESTROY sub-request of UMTXOPSHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTXSHMDESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape.
