Descripción técnica

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.

———ConnMan through 2.0 has a stack-based buffer overflow via a DHCPv6 Reply message. This occurs in get_domains in gdhcp/client.c. It copies a fixed NS_MAXDNAME (1025) bytes from a DHCPv6 DOMAIN_LIST (option 24) value into a 1026-byte stack buffer dns_name regardless of the actual option length, then walks DNS labels with an unbounded "c += jump + 1" loop. A crafted DHCPv6 REPLY with a DOMAIN_LIST option of >= 1025 non-zero bytes makes the label walk leave the buffer and read/write '.' past its end in attacker-chosen strides. An on-link attacker can trigger this without authentication via a forged Router Advertisement (O=1) and a forged DHCPv6 REPLY matching xid/CLIENTID with a long DOMAIN_LIST. The impact is unauthenticated on-link crash of connmand (runs as root). This was introduced in bb06c47.3h CVE-2026-539219.8 CRÍ

———odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA response handler writes past the end of a fixed 512-byte stack buffer (pdbuf) when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two independent overflow sites exist in the same call chain, both reachable from the network via a single unauthenticated UDP packet. odhcpd runs as root on OpenWrt; embedded targets often lack stack canaries and ASLR, making code execution realistic. This issue has been patched in version 25.12.7h CVE-2026-961857.5 ALT
