Description

A flaw was found in the Linux kernel's uvcvideo module. This vulnerability occurs when the start_streaming() function fails to return queued buffers due to an error in uvc_pm_get(). A local attacker could potentially trigger this condition, leading to system instability or a denial of service (DoS) by causing the USB host controller to fail and disconnect USB devices. This issue can result in unexpected system behavior and disruption of normal operations.
