Intel(R) IPP Cryptography software library: Generation of Weak Initialization Vector (IV)
CVE-2022-26083 is a high-severity generation of weak initialization vector (IV) vulnerability in Intel(R) IPP Cryptography software library, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Intel(R) IPP Cryptography software library versions: before version 2021.5. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.18% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Integrated Performance Primitives Cryptography to 2021.5 or a later version.
- Read the advisory on intel.com for workarounds and exact fixed builds.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Intel(R) IPP Cryptography software library | Intel(R) IPP Cryptography software library | before version 2021.5 | Not stated |
| Intel | Integrated Performance Primitives Cryptography | before 2021.5 | 2021.5 |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.
How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- HighSuccess depends on conditions outside the attacker's control.
- Privileges required
- LowA basic user account is enough.
- User interaction
- NoneNo action by a victim is required.
- Scope
- ChangedThe attack can reach beyond the vulnerable component into other systems.
- Confidentiality
- HighAll data handled by the component can be read.
- Integrity
- HighData or code can be modified at will.
- Availability
- NoneAvailability is not affected.

Official description
Generation of weak initialization vector in an Intel(R) IPP Cryptography software library before version 2021.5 may allow an unauthenticated user to potentially enable information disclosure via local access.

The underlying weakness: Generation of Weak Initialization Vector (IV)
The product uses a cryptographic primitive that uses an Initialization Vector (IV), but the product does not generate IVs that are sufficiently unpredictable or unique according to the expected cryptographic requirements for that primitive.
