CVE-2026-43223

CVE-2026-43223 concerns the Linux kernel media driver pvrusb2. The issue arises when pvr2_send_request_ex() submits a write URB and, if the subsequent read URB submission fails (e.g., due to -ENOMEM), returns early without waiting for the write to complete. Because the same URB structure is reuse...
