An issue was discovered in Wi-Fi in Samsung Mobile Processor Exynos 850, 1280, 1330, 1380, 1480, 2400, W920, and W930. A malformed Netlink command can trigger an out-of-bounds read, potentially leading to information leakage.
AnalysisAI
Out-of-bounds read in the Wi-Fi driver subsystem of Samsung Exynos mobile processors allows a local low-privileged attacker to leak kernel memory by sending a malformed Netlink command, potentially exposing sensitive in-kernel data. Affected processors span Samsung's mid-range and flagship mobile lineup plus wearable chips: Exynos 850, 1280, 1330, 1380, 1480, 2400, W920, and W930. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution on the device with at least low-privilege application access (PR:L, AV:L) and the ability to open and write to a Netlink socket that reaches the Wi-Fi driver subsystem. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 2.8 score with vector AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N accurately captures the highly constrained exploitation conditions: local-only access, high attack complexity requiring precision payload crafting, and the need for at least low-privilege code execution on the target device. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Samsung security update documented at https://semiconductor.samsung.com/support/quality-support/product-security-updates/cve-2026-33962/. … Detailed patch versions, workarounds, and compensating controls in full report. |
