CVE-2023-54089

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

virtio_pmem: add the missing REQ_OP_WRITE for flush bio

When doing mkfs.xfs on a pmem device, the following warning was

The root cause is that submit_bio_noacct() needs bio_op() is either WRITE or ZONE_APPEND for flush bio and async_pmem_flush() doesn't assign REQ_OP_WRITE when allocating flush bio, so submit_bio_noacct just fail the flush bio.

Simply fix it by adding the missing REQ_OP_WRITE for flush bio. And we could fix the flush order issue and do flush optimization later.
