CWE
  • CWE-415 - Double Free
  • CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Summary
NetBSD prior to commit ec8451e contains a race condition vulnerability in cryptodev_op() within the opencrypto subsystem that allows local attackers to trigger a double-free condition by concurrently issuing CIOCCRYPT operations on the same session identifier on SMP systems. Attackers can exploit mutable per-operation state embedded in the csession struct to corrupt kernel heap memory.
