  - CVE-2025-1051: The flaw exists within the processing of ALAC data. The issue results from the
  lack of proper validation of the length of user-supplied data prior to copying it to a heap-based
  buffer. An attacker can leverage this vulnerability to execute code in the context of the anacapa
  user.

  - CVE-2026-4149: The specific flaw exists within the handling of the DataOffset field within SMB
  responses. The issue results from the lack of proper validation of user-supplied data, which can
  result in a memory access past the end of an allocated buffer. An attacker can leverage this
  vulnerability to execute code in the context of the kernel.");
