CVE-2026-5910 is an integer overflow vulnerability (CWE-472) in the Media component of Google Chrome prior to version 147.0.7727.55. Published on 2026-04-08, the flaw enables a remote attacker to potentially trigger heap corruption by processing a crafted video file. Chromium rates its security severity as Low, though the CVSS v3.1 base score is 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A remote attacker can exploit this vulnerability over the network with low attack complexity and no privileges required, but it depends on user interaction such as opening a malicious video file in an affected Chrome browser. Successful exploitation could lead to high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary code execution or other severe effects via heap corruption.
The Chrome Releases blog announces the stable channel update for desktop to version 147.0.7727.55, which patches this issue. Additional technical details and the fix are documented in the Chromium issue tracker at https://issues.chromium.org/issues/485212874.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require server-side validation of all inputs instead of trusting client-supplied immutable parameters.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Secure coding standards require server-side verification of client-supplied data, eliminating the root cause of external control of immutable parameters.
Security testing in development and acceptance will detect parameter tampering vulnerabilities before deployment.
Secure development lifecycle mandates input validation and integrity checks that directly prevent external tampering of assumed-immutable parameters.
Application security requirements explicitly call for validation of all inputs, including hidden fields, mitigating CWE-472.
Information access restriction can limit which parameters users may influence, providing a secondary layer of defense.
