  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: pvrusb2: fix URB leak in pvr2_send_request_ex\n\nWhen pvr2_send_request_ex() submits a write URB successfully but fails to\nsubmit the read URB (e.g. returns -ENOMEM), it returns immediately without\nwaiting for the write URB to complete. Since the driver reuses the same\nURB structure, a subsequent call to pvr2_send_request_ex() attempts to\nsubmit the still-active write URB, triggering a 'URB submitted while\nactive' warning in usb_submit_urb().\n\nFix this by ensuring the write URB is unlinked and waited upon if the read\nURB submission fails.",
