CVE-2026-64034

A flaw was found in the Linux kernel's mana network driver. This Time-of-Check to Time-of-Use TOCTOU vulnerability allows a hardware component to modify a message identifier hwcmsgid in Direct Memory Access DMA memory after it has been validated but before it is used. This manipulation bypasses...

CVE-2026-64018

A flaw was found in the Linux kernel's mana network driver. In Confidential Virtual Machines VMs, a missing bounds check when processing network events can allow a malicious hardware component or a compromised VM to write data outside of an intended memory region. This out-of-bounds access could...
