CVE-2025-7700: NULL Pointer Dereference
A flaw was found in FFmpeg’s ALS audio decoder, where it does not properly check for memory allocation failures. This can cause the application to crash when processing certain malformed audio files. While it does not lead to data theft or system control, it can be used to disrupt services and cause a denial of service.
AI Analysis
Technical Summary
This vulnerability arises from FFmpeg's ALS audio decoder failing to properly check for memory allocation failures, which can cause a NULL pointer dereference. When certain malformed audio files are processed, this leads to application crashes and denial of service conditions. The CVSS 3.1 base score is 5.3, reflecting a network attack vector with low complexity and no privileges or user interaction required. Confidentiality and integrity impacts are none, with only availability affected.
Potential Impact
The impact is limited to denial of service by crashing the application processing audio files. There is no impact on confidentiality or integrity, and no evidence of exploitation in the wild. This could disrupt services relying on FFmpeg for audio decoding but does not lead to data compromise or system takeover.
Mitigation Recommendations
Patch status is not confirmed from the provided vendor advisory content. Users should consult the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2025-7700 for the latest remediation guidance. Until an official fix is applied, consider restricting or validating input audio files to mitigate potential denial of service.
