CVE-2026-80615

A flaw was found in the Linux kernel's dstmetadata component. When copying tunnel information and options within the tundstunclone function, a compiler warning for a potential memory buffer overflow is triggered. This warning is a false positive, as memory is correctly allocated, but it can lead ...

Linux Distros Unpatched Vulnerability : CVE-2026-80615
