What is CVE-2026-115485?
CVE-2026-115485 is a medium-severity vulnerability in Red Hat Enterprise Linux 10, published on 23 Oct 2026.
Official description
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.
Weakness: CWE-125
