CVE-2026-24288: CWE-122: Heap-based Buffer Overflow in Microsoft Windows 10 Version 21H2
Heap-based buffer overflow in Windows Mobile Broadband allows an unauthorized attacker to execute code with a physical attack.
AI Analysis
Technical Summary
This vulnerability involves a heap-based buffer overflow in the Windows Mobile Broadband feature of Windows 10 Version 21H2 (build 10.0.19044.0). An attacker with physical access could exploit this flaw to execute arbitrary code on the affected system. The CVSS vector indicates the attack requires physical access (AV:P), has low attack complexity (AC:L), requires no privileges (PR:N) or user interaction (UI:N), and impacts confidentiality, integrity, and availability with high severity. The vulnerability is tracked as CWE-122. A patch is available from Microsoft to remediate this issue.
Potential Impact
Successful exploitation could lead to arbitrary code execution by an attacker with physical access, potentially compromising system confidentiality, integrity, and availability. However, the attack vector requires physical access, limiting remote exploitation possibilities. 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 21H2 (build 10.0.19044.0) to remediate this issue. Since the vulnerability requires physical access, controlling physical device access also helps mitigate risk.
