Out-of-bounds write in libpadm.so library prior to SMR Jul-2026 Release 1 allows local attackers to execute arbitrary code.
AnalysisAI
Arbitrary code execution in Samsung's libpadm.so system library on Galaxy devices allows a local, low-privileged attacker to corrupt memory via an out-of-bounds write and run code in the context of the vulnerable component prior to the SMR Jul-2026 Release 1. The flaw was reported internally by Samsung Mobile Security and carries a CVSS 4.0 base score of 8.4 (high). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the device and pre-existing low-level privileges (CVSS PR:L) - typically an already-installed app or on-device code that can reach and pass crafted input to the libpadm.so library; it is not remotely exploitable over the network (AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N, VC:H/VI:H/VA:L) describes a local attack requiring some existing privilege but no user interaction and low complexity, yielding high confidentiality and integrity impact for a score of 8.4. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A user installs a malicious or trojanized app that already holds modest on-device privileges; the app feeds crafted input to a component backed by libpadm.so, triggering the out-of-bounds write to overwrite memory and execute attacker-controlled code, escalating beyond its sandbox. Because the CVSS vector is local, low-complexity, and needs no user interaction, exploitation is reliable once code runs on the device, though no public POC is currently known. |
| Remediation | Apply Samsung's Security Maintenance Release SMR Jul-2026 Release 1 or later via Settings > Software update on the device, or through the carrier/enterprise MDM update channel; this is the vendor-released patch that closes the out-of-bounds write. … Detailed patch versions, workarounds, and compensating controls in full report. |
