Summary

CVE-2024-20011 is a critical-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Google Android. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 9.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

In the ALAC decoder, an incorrect bounds check creates a vulnerability that can result in information disclosure and potentially remote code execution. The issue is tracked as CVE-2024-20011 with a CVSS score of 9.8 and is associated with CWE-119. It affects MediaTek components that incorporate the ALAC decoder, as indicated by the Patch ID and Issue ID ALPS08441146.

An unauthenticated attacker can exploit the flaw over the network without user interaction or additional privileges. Successful exploitation grants the ability to disclose sensitive information and achieve remote code execution, which carries high impact across confidentiality, integrity, and availability.

MediaTek's February 2024 product security bulletin references the same Patch ID ALPS08441146 as the fix for this issue. The EPSS score has remained flat at 0.0615 with no material increase since disclosure.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-119

Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.

addresses: CWE-119

Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.

addresses: CWE-119

Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.

addresses: CWE-119

Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
