CyberRota Analysis
AI-GeneratedThe vulnerability affects the COMPAT_NETBSD32 compatibility layer in NetBSD, allowing local users to exploit a use-after-free and double-free condition in the msg_recv_copyin() function. By invoking recvmsg() with an appropriate msg_iovlen, an attacker can induce a kernel panic or memory corruption, potentially compromising system stability. System administrators and security teams managing 64-bit NetBSD systems should prioritize patching to mitigate this high-severity risk.
Original NVD Description
NetBSD contains a use-after-free and double-free vulnerability in msg_recv_copyin() within the COMPAT_NETBSD32 compatibility layer due to a missing return statement before the cleanup label on the success path. Any local user able to execute a 32-bit binary on a 64-bit NetBSD system can trigger a kernel panic or memory corruption by calling recvmsg() with msg_iovlen between 9 and IOV_MAX, causing the kernel to access a freed iovec buffer and subsequently free the same allocation a second time.
