CVE-2025-22885
Description
Improper buffer restrictions in the firmware for the TDX Module may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. 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 (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Improper buffer restrictions in Intel TDX Module firmware allow local privilege escalation.
Vulnerability
Overview CVE-2025-22885 is a vulnerability in the firmware of the Intel Trust Domain Extensions (TDX) Module, caused by improper buffer restrictions. This flaw could allow a privileged system software adversary to escalate privileges, though the attack is considered high complexity and requires local access [1].
Exploitation
Conditions Exploitation requires the attacker to have a privileged user position on the system and perform a high-complexity attack. No user interaction is needed, and the attacker does not need special internal knowledge if the attack prerequisites are met. The attack vector is local, meaning the adversary must already have some level of system access [1].
Impact
If successfully exploited, the vulnerability could lead to a breach of confidentiality (high impact) and integrity (low impact), but does not affect availability. Notably, the secondary impacts on subsequent systems are listed as none, suggesting the escalation is contained within the TDX Module [1].
Mitigation
Intel has released a security advisory (INTEL-SA-01314) with firmware updates to address this issue. Affected users should apply the recommended updates to mitigate the risk [1].
