CVE-2026-112283: Memory Allocation with Excessive Size Value in VideoLAN libbluray
Description
VideoLAN libbluray through version 1.5.1 has a vulnerability in the _parse_extent_start_points() function where the num_point field is used without bounds checking. This allows an attacker to supply a crafted .clpi file with a large num_point value, leading to uncontrolled memory allocation and CPU exhaustion, resulting in a denial of service condition.

Technical Analysis
CVE-2026-112283 describes an uncontrolled memory allocation vulnerability in VideoLAN libbluray versions up to 1.5.1. The vulnerability exists in the _parse_extent_start_points() function within clpi_parse.c, where the num_point field from a .clpi file is trusted without validating its size. An attacker can exploit this by providing a specially crafted .clpi file on a disc, image, or directory that specifies an excessively large num_point value. This causes the software to allocate excessive memory and consume CPU resources, leading to a denial of service.
Potential Impact
Successful exploitation can cause the libbluray library to exhaust system memory and CPU resources, resulting in denial of service. There is no indication of privilege escalation, code execution, or data disclosure from the provided information.
Mitigation Recommendations
No explicit patch or remediation details are provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted or unauthenticated .clpi files from untrusted sources to reduce risk.
