Answer in brief
CVE-2026-104115 records a Medium severity (CVSS 5.4) vulnerability in Stack buffer overflow in illumos reparsed nfs-basic plugin allows local users to crash the daemon. The current sources do not mark it as known exploited. The current feed maps OmniOS/OmniOS (generic), illumos/service/file-system/nfs (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A stack-based buffer overflow in the illumos reparse point daemon (reparsed) allows a local user to crash the daemon. get_fs_locations() in usr/src/cmd/fs.d/nfs/rp_basic/libnfs_basic.c, part of the nfs-basic reparse plugin, copies the host and path components of a reparse string into a fixed 1024-byte stack buffer without checking their length. The reparsed door at /var/run/reparsed_door is readable by all users and the door server does not check the caller's credentials, so an unprivileged local user can send an nfs-basic request with an overlong host or path component to overflow the buffer. On systems built with stack protection, which is the default, this causes reparsed to abort; repeated requests place the svc:/system/filesystem/reparse service into maintenance. The service is disabled by default. The flaw has existed since 2009 (illumos-gate commit 2f172c55), and affects any illumos distribution prior to illumos-gate commit 6a2df4aa.
