AI Analysis

Impact

The vulnerability is an out-of-bounds write in SveService prior to SMR May‑2026 Release 1. It allows local privileged attackers to execute arbitrary code, potentially compromising the device’s data, confidentiality, and integrity.

Affected Systems

Samsung Mobile Devices running firmware versions before SMR May‑2026 Release 1 are affected; any device that has not upgraded to the indicated release or newer contains the flaw.

Risk and Exploitability

With a CVSS score of 6.8 the risk is moderate; the EPSS score is not available and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires local privileged access, so an attacker must already have some level of local control on the device before abusing the out‑of‑bounds write.

Generated by OpenCVE AI on May 13, 2026 at 07:24 UTC.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest Samsung firmware update (SMR May‑2026 Release 1 or newer) from the official Samsung security update portal.
  • Disable or restrict local services that provide access to SveService to reduce the attack surface.
  • If the device is managed by an MDM, enforce installation of the latest firmware and block older firmware versions.
