CVE-2023-28746
Information exposure through microarchitectural state after transient execution from some register files for some Intel(R) Atom(R) Processors may allow an authenticated user to potentially enable
02 Description
Information exposure through microarchitectural state after transient execution from some register files for some Intel(R) Atom(R) Processors may allow an authenticated user to potentially enable
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.54% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 45.4% of scored records. A rank, not a probability.
- NVD base score
- 6.5 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
- NVD analysis status
- Deferred. NVD last modified this record on 2026-10-14.
- Red Hat severity
- Moderate. Red Hat's rating for its own products, not a CVSS rating.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
