Overview

CVE-2024-57793 is a critical-severity vulnerability. It was published on January 11, 2025 and has a CVSS 3.1 base score of 9.3 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.3, rated CRITICAL. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

virt: tdx-guest: Just leak decrypted memory on unrecoverable errors

In CoCo VMs it is possible for the untrusted host to cause

set_memory_decrypted() to fail such that an error is returned

and the resulting memory is shared. Callers need to take care

to handle these errors to avoid returning decrypted (shared)

memory to the page allocator, which could lead to functional

or security issues.

Leak the decrypted memory when set_memory_decrypted() fails,

and don't need to print an error since set_memory_decrypted()

will call WARN_ONCE().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
