CVE-2026-115485 analysis covering impact, affected products, versions, remediation, and cross-checked defender guidance.
CVE-2026-115485 is a vulnerability published by NVD on 10/23/2026.
What happened
A flaw was found in the iscsiuio component of open-iscsi. The DHCPv6 option parser calls strlen() on raw network data without ensuring a NUL terminator is present, causing it to read past the buffer into heap memory. This can result in a daemon crash, a 1-byte heap overwrite, or corruption of the iSCSI initiator name. An attacker on the same network segment can trigger this by sending a crafted DHCPv6 Advertise message.
