Overview<\/strong><\/p>\n

This report provides an in-depth analysis of a critical vulnerability, CVE-2025-26455, that resides in multiple functions of NdkMediaCodec.cpp. This vulnerability, if exploited, could lead to local privilege escalation, potentially resulting in a total system compromise or significant data leakage. Affected entities are advised to apply necessary patches or implement temporary mitigation measures to prevent potential exploitation.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-26455
\nSeverity: High (CVSS 7.8)
\nAttack Vector: Local
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Local escalation of privileges potentially leading to system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

NdkMediaCodec.cpp | All prior versions<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from improper boundary checking in multiple functions<\/a> within NdkMediaCodec.cpp. This allows for an out-of-bounds write due to a heap buffer<\/a> overflow, leading to an unexpected behavior of the software, potentially allowing malicious actors to escalate their privileges within the system. As no user interaction is required, this vulnerability can be exploited autonomously, increasing its potential impact.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual illustration of how this vulnerability<\/a> might be exploited. This is not an actual exploit code, but a simplified representation for understanding:
\n“`c++
\n#include
\n#include
\nint main() {
\nchar buffer[10];
\n\/\/ Heap buffer overflow vulnerability<\/a>
\nstd::strcpy(buffer, “A very long string causing overflow”);
\nstd::cout << buffer << std::endl;\nreturn 0;\n}\n```\nIn the above example, an extended string is copied to a buffer that can only hold 10 characters. This results in a heap buffer overflow, potentially leading<\/a> to unpredictable behavior or privilege escalation.<\/p>\n

Mitigation Guidance<\/strong><\/p>\n

Affected entities are advised to apply the vendor-supplied patch immediately to fix this vulnerability. In cases where immediate patching is not feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure until patches can be applied. Regularly updating and patching systems, as well as monitoring for any unusual activity, are essential steps in maintaining a secure system environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
