Incomplete in the CWE catalog · 4 CVEs mapped
A processor event or prediction may allow incorrect operations (or correct operations with incorrect data) to execute transiently, potentially exposing data over a covert channel.
A transient execution vulnerability within AMD CPUs may allow a local user-privileged attacker to leak data via the floating point divisor unit, potentially resulting in loss of confidentiality.
Exposure of sensitive information during transient execution for some TDX within Ring 0: Hypervisor may allow an information disclosure. Authorized adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
A transient execution vulnerability in some AMD processors may allow a user process to infer the control registers speculatively even if UMIP feature is enabled, potentially resulting in information leakage.
