Description
In the Linux kernel, the following vulnerability has been resolved:
vfio/qat: fix f_pos race in qat_vf_resume_write()
qat_vf_resume_write() checks filp->f_pos before taking migf->lock, but
copies into the migration-state buffer after taking the lock and
re-reading the shared file position.
Two concurrent writers could therefore pass the bounds check with the
old offset, then have the second writer copy after the first advanced
f_pos, writing past the end of the migration-state buffer.
Take migf->lock before doing the boundary checks.
