CVE-2026-72018

A flaw was found in the Linux kernel's dibs: loopback functionality. A missing bounds check in the movedata function allows an attacker to provide an out-of-bounds offset or an oversized write. This can lead to an out-of-bounds write past an allocated kernel buffer, potentially causing memory...
