Subject: Re: CVE-2017-12190: Linux kernel: block: memory leak
when merging small consecutive buffers in SCSI IO vectors
Hello,
A patch fixing this issue was accepted upstream:
commit 95d78c28b5a85bacbc29b8dba7c04babb9b0d467 fix unbalanced page refcounting in bio_map_user_iov
I would also consider next 2 related patches if backporting:
commit 2b04e8f6bbb196cab4b232af0f8d48ff2c7a8058 more bio_map_user_iov() leak fixes
commit 1cfd0ddd82232804e03f3023f6a58b50dfef0574 bio_copy_user_iov(): don't ignore ->iov_offset #v4.5+
