About this tag
CVE-2024-56712 is a low-severity memory leak vulnerability in the Linux kernel's udmabuf driver. The bug occurs in the export path when file-descriptor assignment fails, leaving orphaned dma_buf objects. A small patch closes the leak by ensuring proper cleanup. While not critical, the issue matters for systems that repeatedly hit file-descriptor limits or expose udmabuf to untrusted local code. This tag covers discussion of the vulnerability, its fix, and implications for kernel stability and security.
