Description

In the Linux kernel, the following vulnerability has been resolved:  scsi: bsg: Fix TOCTOU in io_uring passthrough command setup  scsi_bsg_uring_cmd() reads bsg_uring_cmd from the shared mmap'd SQE. Userspace can change a field after we check it and before we use it. request_len is the sharp case: it can grow past sizeof(scmd->cmnd) after the bound check and overflow scmd->cmnd in copy_from_user().  READ_ONCE() the SQE fields we check or use into locals before use.
