CVE-2026-20828: CWE-125: Out-of-bounds Read in Microsoft Windows 10 Version 1607
Out-of-bounds read in Windows Internet Connection Sharing (ICS) allows an unauthorized attacker to disclose information with a physical attack.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read (CWE-125) in the Windows ICS feature on Windows 10 Version 1607 (build 10.0.14393.0). An attacker with physical access can exploit this flaw to read memory outside the intended bounds, potentially disclosing sensitive information. The CVSS vector indicates the attack requires physical access (AV:P), low attack complexity (AC:L), no privileges (PR:N), and no user interaction (UI:N). The impact is confidentiality loss (C:H) without integrity or availability impact. The vulnerability is officially published and a patch is available.
Potential Impact
An attacker with physical access to a vulnerable Windows 10 Version 1607 system can exploit this out-of-bounds read to disclose sensitive information from memory. There is no impact on system integrity or availability. No known exploits are currently reported in the wild.
Mitigation Recommendations
A patch is available for this vulnerability. It is recommended to apply the official Microsoft update for Windows 10 Version 1607 to remediate this issue. Since the vulnerability requires physical access, limiting physical access to affected systems also reduces risk.
