CVE-2026-43255

In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: fix WARNING in usbtxblock The function usbtxblock submits cardp-txurb without ensuring that any previous transmission on this URB has completed. If a second call occurs while the URB is still active e.g. during...

CVE-2026-43223

In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix URB leak in pvr2sendrequestex When pvr2sendrequestex submits a write URB successfully but fails to submit the read URB e.g. returns -ENOMEM, it returns immediately without waiting for the write URB to complete...

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...
