CVE-2026-112283 · Severity: medium · CVSS 5.5 · Published 2026-10-19

VideoLAN libbluray is a library that decodes and plays Blu-ray discs. A vulnerability in how it parses Blu-ray clip information files allows an attacker to craft a malicious disc or image that causes the application to allocate excessive memory and CPU resources, leading to system slowdown or crash.

## Technical details

The _parse_extent_start_points() function in clpi_parse.c fails to validate the num_point field before using it to allocate memory, allowing an attacker to trigger unbounded memory allocation. The vulnerability is triggered by supplying a crafted .clpi file with an extremely large num_point value on a disc, image, or directory. This results in denial of service through memory and CPU exhaustion.
