CVE-2026-31585
Description
A flaw was found in the Linux kernel's vidtv media driver. When the vidtv_start_streaming() function fails, the internal counter for active streams (nfeeds) is not properly decremented. This state corruption can lead to memory leaks and prevent proper cleanup of resources, potentially causing system instability or a denial of service (DoS).
