A use-after-free vulnerability exists in the DICOM Element Parsing as implemented in Imaging Data Commons libdicom 1.0.5. A specially crafted DICOM file can cause premature freeing of memory that is used later. To trigger this vulnerability, an attacker would need to induce the vulnerable application to process a malicious DICOM image.The Use-After-Free happens in the `parse_meta_element_create()` parsing the elements in the File Meta Information header.

umtx Kernel panic or Use-After-Free

Concurrent removals of certain anonymous shared memory mappings by using the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM 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 UMTX_SHM_DESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape.
