PatchTheCVECVE-2026-115484: A flaw was found in the iscsiuio component of open-iscsi
CVE-2026-115484 is a high-severity flaw (CVSS 7.6) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
A fixed release or distro patch exists.
