Privileged code execution via DXE out-of-bounds write
Published Jul 24, 2024 · Updated Aug 2, 2024
Out-of-bounds write in the Dell Edge Gateway 3200 DXE driver before 1.03.10 allows local users to execute arbitrary UEFI code. Dell identifies the affected locus as a DXE driver but has not disclosed the buffer, write operation, or attacker-controlled input. Exploitation requires local authenticated access with high privileges and can expose UEFI code, execute arbitrary code, or escalate privilege.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <1.03.10
- Affected versionversion=N/A <v1.03.10
