Description
A flaw was found in the Linux kernel's media subsystem, specifically within the rtl2832_sdr driver. When the start_streaming() function encounters an error, it fails to properly return buffers that were previously queued. This oversight can lead to a memory leak, potentially resulting in resource exhaustion and a Denial of Service (DoS) for the system.
