CVE-2025-56226: n/a
CVE-2025-56226 is a medium severity memory leak vulnerability in Libsndfile version 1.2.2 and earlier. The issue exists in the mpeg_l3_encoder_init() function within the mpeg_l3_encode.c source file. This vulnerability does not impact confidentiality or integrity but can cause resource exhaustion due to leaking memory. There are no known exploits in the wild and no patch or official remediation information is currently available.
AI Analysis
Technical Summary
Libsndfile versions up to 1.2.2 contain a memory leak vulnerability in the mpeg_l3_encoder_init() function located in the mpeg_l3_encode.c file. The vulnerability is classified under CWE-401 (Improper Release of Memory Before Removing Last Reference). The CVSS v3.1 base score is 5.3, reflecting a network attack vector with low complexity, no privileges required, no user interaction, and impact limited to availability (memory leak). No patch or vendor advisory is currently provided.
Potential Impact
The vulnerability causes a memory leak which can degrade system availability by exhausting memory resources over time. There is no impact on confidentiality or integrity. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should monitor memory usage when using the affected function and consider limiting exposure to untrusted inputs that invoke the vulnerable code.
