CVE-2026-64534

A flaw was found in the Linux kernel's NVMe over TCP target nvmet-tcp implementation. When a data digest mismatch is detected, nvmetrequninit is called unconditionally, but if the command was already in the INITFAILED state, the matching percpureftrygetlive was never performed. The resulting...
