CVE-2025-22919 is a medium-severity vulnerability discovered in FFmpeg, specifically in the git-master commit N-113007-g8d24a28d06. This vulnerability allows attackers to cause a denial of service (DoS) by opening a crafted AAC file. The CVSS score for this vulnerability is 6.5, indicating a moderate level of concern for organizations reliant on FFmpeg for media processing. Given its nature, attackers may exploit this flaw to disrupt services, which could have significant ramifications for affected users.
The vulnerability is classified under CWE-617, which pertains to reachable assertions. The impact is particularly high in terms of availability, as successful exploitation could cause the application to crash or become unresponsive. Organizations using FFmpeg should be aware of the potential risks associated with this vulnerability and take appropriate measures to mitigate them.
Currently, there is no known public exploit for CVE-2025-22919, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, given the circumstances and the ease of triggering a DoS through a crafted AAC file, it remains crucial for defenders to prioritize remediation efforts. Organizations should address this vulnerability in their patch cycle to prevent potential disruptions.
Organizations should prioritize patching immediately. Moreover, they should consider employing security measures that monitor the handling of media files by FFmpeg to detect any anomalies that may indicate an attempted exploitation.
Vulnerability Details
The CVE description succinctly states that this vulnerability allows attackers to cause a denial of service via opening a crafted AAC file. The vulnerability type is classified as a denial of service, with a CVSS score of 6.5, indicating a medium severity. The affected product is FFmpeg, and it was first published on February 18, 2025.
Technical Analysis
The root cause of this vulnerability lies in a reachable assertion within the code when handling AAC files. This issue can lead to a denial of service when an attacker manages to execute the specific sequence that triggers the fault in the assertion.
The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely by sending a crafted AAC file over the network. The complexity of the attack is low, requiring no special privileges to exploit the vulnerability. However, user interaction is required, as a victim must open the crafted file.
The availability impact of this vulnerability is high, as it can crash the application or service using FFmpeg. There are no confidentiality or integrity impacts associated with this vulnerability, making it primarily an availability concern.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-22919 includes potential service outages, which could lead to significant disruptions for organizations that rely on FFmpeg for media processing. The blast radius includes any application or service that utilizes FFmpeg's capabilities, potentially affecting a wide range of operations.
Organizations should address this vulnerability in their priority patch cycle, particularly given the potential for denial of service that affects availability. With a CVSS score of 6.5 and an EPSS score in the 0.22 percentile, the urgency for remediation is moderate, but still critical enough to warrant immediate attention.
