Published Sep 16, 2026
Modified Sep 16, 2026
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: bsg: Cap io_uring sense copy to max_response_len Completion copied scmd->sense_len to the user response buffer without honoring max_response_len. After a valid sense, the midlayer sets sense_len to the real length (up to SCSI_SENSE_BUFFERSIZE), so a smaller user buffer was overrun.
