Description

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

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().

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Changed — a successful attack reaches components beyond the vulnerable one.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
