Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an use of uninitialized resource vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to information exposure.
AnalysisAI
Information exposure in Dell PowerProtect Data Domain across multiple release tracks allows a low-privileged local attacker to read sensitive residual data via an uninitialized memory resource (CWE-908). The flaw spans the mainline 7.7.1.0-8.7 branch and three LTS tracks (LTS2024, LTS2025, LTS2026), confirmed by Dell via advisory DSA-2026-278. No public exploit code exists and no active exploitation has been identified; the CVSS 3.3 score and local-only attack vector place this firmly in the low-severity tier.
Technical ContextAI
CWE-908 (Use of Uninitialized Resource) describes a class of defect where software reads from a memory buffer, variable, or data structure before assigning it a valid value, potentially exposing residual contents from prior operations. Dell PowerProtect Data Domain is a purpose-built backup and deduplication appliance widely deployed as a protection storage target. The CVSS vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N confirms the flaw is exercisable only from a local session with at least low-level privileges, results in limited confidentiality impact only, and does not cross a trust boundary (S:U). No CPE strings were provided in the input, but the affected product family is unambiguously identified by Dell's own disclosure as PowerProtect Data Domain across mainline and LTS release tracks.
RemediationAI
Consult Dell advisory DSA-2026-278 at https://www.dell.com/support/kbdoc/en-us/000481268/dsa-2026-278-security-update-for-dell-powerprotect-data-domain-multiple-vulnerabilities for the specific fixed versions applicable to each release track. Exact patched version numbers were not included in the available input data and must be confirmed directly from the advisory before planning upgrades. As a compensating control where patching is deferred, restrict local shell and administrative access to the Data Domain appliance strictly to authorized personnel - this directly addresses the PR:L local-access prerequisite and eliminates the exploitation surface for untrusted users. Note that this control does not remediate the underlying defect and should not substitute for patching.
