CVE-2025-69649:
  Null pointer dereference in readelf before 2.46 results in segfault when
  processing a crafted ELF binary with malformed header fields.
  No evidence of memory corruption beyond the null pointer dereference, nor
  any possibility of code execution, was observed.

CVE-2025-69652:
  Null pointer dereference in readelf when processing a crafted ELF binary
  with malformed DWARF abbrev or debug information which leads to SIGABORT.
  No evidence of memory corruption or code execution was observed; the impact
  is limited to denial of service.
