Multiple integer signedness errors in smb_subr.c in the netsmb module in the kernel in NetBSD 5.0.2 and earlier, FreeBSD, and Apple Mac OS X allow local users to cause a denial of service (panic) via a negative size value in a /dev/nsmb ioctl operation, as demonstrated by a (1) SMBIOC_LOOKUP or (2) SMBIOC_OPENSESSION ioctl call.

Security readout for executives and security teams

This is a local denial-of-service flaw in BSD-derived SMB kernel support. A user with local access could trigger a kernel panic, crashing the system. The sources describe NetBSD 5.0.2 and earlier, FreeBSD, and Apple Mac OS X, but do not provide a modern exploit status or complete fix matrix. Exposure is most relevant on older NetBSD, FreeBSD, or Apple Mac OS X systems with netsmb available and untrusted local users. Network-only attackers are not described in the sources. Treat as a targeted availability risk for legacy or multi-user systems, not an internet-wide emergency. Prioritize systems where untrusted local users can access older BSD or Mac OS X hosts. Mitigation focus: Check vendor guidance for affected NetBSD, FreeBSD, and Apple Mac OS X releases.; Apply vendor-provided kernel or system updates where available.; Reduce local account access on systems that expose netsmb functionality..
