AI Analysis
Technical Summary
This vulnerability affects the core component of Oracle VM VirtualBox version 7.2.6. It can be exploited remotely without authentication via the RDP protocol to cause a denial of service by hanging or repeatedly crashing the application. The CVSS 3.1 base score is 7.5, reflecting high impact on availability with no impact on confidentiality or integrity. The vulnerability is categorized under CWE-284 (Improper Access Control). The vendor advisory is a general Critical Patch Update for multiple Oracle products but does not explicitly confirm patch availability for this specific issue.
Potential Impact
Successful exploitation results in a denial of service condition causing Oracle VM VirtualBox to hang or crash repeatedly, impacting availability. There is no impact on confidentiality or integrity. No reports of active exploitation in the wild are known.
Mitigation Recommendations
Oracle has released a Critical Patch Update advisory covering multiple vulnerabilities across Oracle products. However, the advisory does not explicitly confirm a patch or fix for CVE-2026-35245. Patch status is not yet confirmed—users should monitor the Oracle advisory at https://www.oracle.com/security-alerts/cpuapr2026.html for updates and apply patches promptly once available. Until then, limiting network access to RDP interfaces of Oracle VM VirtualBox instances can reduce exposure.
