CVE-2023-53769 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: virt/coco/sev-guest: Double-buffer messages The encryption algorithms read and write directly to shared unencrypted memory, which may leak information as well as permit the host to tamper with the message integrity. Instead, copy whole messages in or out as needed before doing any computation on them.. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
