CVE-2026-115484 · Open-iscsi: open-iscsi: dhcpv4 option parser heap out-of-bounds read in iscsiuio parse_msg
This page contains facts from public vulnerability sources. Check the original advisory before updating.
A flaw was found in the iscsiuio component of open-iscsi. The DHCPv4 option parser incorrectly calculates the length of the options data, causing it to read beyond the allocated buffer into adjacent heap memory. An attacker on the same network segment can send a crafted DHCP response to crash the daemon or corrupt its network configuration.
