CVE-2026-33960 Samsung CVE debrief

A denial of service vulnerability was found in Samsung Mobile Processor and Wearable Processor Exynos 1330, 1380, 1480, 1580, 1680, W920, W930, and W1000. A malformed ioctl command to the Wi-Fi interface device can lead to improper buffer size allocation, resulting in an out-of-bounds write. This issue could disrupt system availability, emphasizing the need for defenders to verify exposed systems and apply patches promptly. The vulnerability's impact on system operations should be carefully assessed, and affected components should be identified for immediate remediation.

Who should care

Defenders responsible for Samsung Mobile Processor and Wearable Processor Exynos systems should assess exposure and prioritize patching. This includes operators managing affected platforms, vulnerability management teams, and security teams responsible for ensuring system integrity. They should verify exposed systems, review system configurations, and apply patches promptly to prevent potential disruption. Additionally, defenders should monitor for unusual

Why it matters

CVE-2026-33960 is a denial of service vulnerability in Samsung Mobile Processor and Wearable Processor Exynos. Defenders should verify exposed systems and apply patches to prevent potential disruption.

  • Denial of service (DoS) could disrupt system availability
  • Verification of exposed systems and patch application is necessary

Technical summary

A malformed ioctl command to the Wi-Fi interface device can lead to improper buffer size allocation, resulting in an out-of-bounds write and causing a denial of service (DoS). This technical issue arises from the improper handling of ioctl commands, which can lead to buffer overflow and subsequent system disruption. Defenders should focus on verifying system configurations and applying necessary patches to mitigate this vulnerability. The technical impact of this vulnerability is significant, as it can lead to system crashes or instability if exploited.

Defensive priority

Defenders should prioritize verifying exposed systems and applying patches.

Recommended defensive actions

  • Verify exposed systems and apply patches
  • Monitor for unusual activity
  • Review system configurations
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and NVD entry provide details on the vulnerability. However, the scope of affected systems and versions requires further verification. Defenders should review the official CVE Program record and NIST NVD detail page for source-provided CVE metadata and specific vulnerability assessments. Additional verification is necessary to determine the full extent of affected systems and to confirm the accuracy of the information provided.
