CVE-2026-112057 VideoLAN CVE debrief

Who should care

Defenders responsible for applications that handle DVD or disc images, especially those using libdvdnav, should assess exposure and prioritize verification and updates. This includes operators, platform administrators, vulnerability management teams, and security teams who need to ensure that libdvdnav is updated to version 7.0.0 or later to mitigate the vulnerability. Additionally, teams responsible for monitoring, detection, and incident response should

Why it matters

Defenders should prioritize verifying and updating libdvdnav to version 7.0.0 or later due to a heap out-of-bounds read vulnerability that could lead to crashes or information disclosure in applications handling DVD or disc images.

• Potential crashes or information disclosure in applications using libdvdnav
• Need to verify and update libdvdnav to version 7.0.0 or later
• Possible exploitation through crafted DVD or disc images

Technical summary

libdvdnav before 7.0.0 contains a heap out-of-bounds read vulnerability in dvdnav_describe_title_chapters. An attacker can provide a crafted DVD or disc image declaring a larger VMGI title vts_ttn than the title set's entries to crash applications enumerating chapters. This vulnerability can lead to crashes or information disclosure in applications handling DVD or disc images. The vulnerability is in the dvdnav_describe_title_chapters function, which does not properly validate the vts_ttn value, allowing for out-of-bounds reads.

Defensive priority

Defenders should prioritize verifying and updating libdvdnav to version 7.0.0 or later, especially in applications that handle DVD or disc images.

Recommended defensive actions

• Verify and update libdvdnav to version 7.0.0 or later
• Review applications that handle DVD or disc images for potential exposure
• Monitor for and address potential crashes or information disclosure
• Perform a thorough review of libdvdnav usage in the environment
• Check for any existing mitigations or compensating controls
• Inventory assets that may be impacted by this vulnerability
• Consider rollback or change windows for updates

Evidence notes
