CVE-2026-73324 · Severity: medium · CVSS 4.3 · Published 2026-09-09

VLC media player, a widely-used application for playing audio and video files, contains a memory safety flaw that can be triggered when processing media from an attacker-controlled network source. An attacker can exploit this by tricking a user into opening a malicious media link, potentially disclosing sensitive data from the player's memory. The impact is limited by the specific build configuration and layout of memory at the time of exploitation.

## Technical details

This vulnerability is a memory-safety defect in VLC versions 3.0.0 through 3.0.23, reachable during the processing of media streams from remote network sources. The vulnerability requires user interaction (opening/playing attacker-supplied media) and is dependent on specific build configurations. Successful exploitation may result in the disclosure of a limited, layout-dependent amount of process memory from the VLC application. The attack vector is network-based, and no patch status is explicitly stated in the advisory, though the version range constraint suggests newer versions may be unaffected.
