CVE-2026-89973

A flaw was found in the Linux kernel's nvme-tcp component. A malicious or misconfigured NVMe controller can send a Controller to Host Data Protocol Data Unit C2HData PDU in response to a write command, which is not properly validated for data direction. This can trigger a kernel warning, leading ...
