Stakeholder-Specific Vulnerability Categorization from CISA's ADP record at CVE.org: whether exploitation is observed, whether an attack can be automated, and how much of the system is at stake. The CVSS score shown above comes from the assigning CNA record, not NVD.
FFmpeg through 9.0.2 contains an uncontrolled memory allocation vulnerability in the Interplay ACM decoder that allows attackers to exhaust memory via an attacker-controlled block size. Attackers can supply a crafted ACM file with maximum level and row count in extradata, making decode_init() allocate nearly a gigabyte and deny service.
