CVE-2017-12190

It was found that in the Linux kernel through v4.14-rc5, biomapuseriov and biounmapuser in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bioaddpcpage merges them into one, but the page reference is never dropped, causing a...

kernel: memory leak when merging buffers in SCSI IO vectors

It was found that in the Linux kernel through v4.14-rc5, biomapuseriov and biounmapuser in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bioaddpcpage merges them into one, but the page reference is never dropped, causing a...

Memory corruption

The biomapuseriov and biounmapuser functions in block/bio.c in the Linux kernel before 4.13.8 do unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bioaddpcpage function merges them into one, but the page reference is never dropped. This...

CVE-2017-12190

CVE-2017-12190 affects the Linux kernel before 4.13.8. The issue arises in the SCSI I/O path where bio_map_user_iov and bio_unmap_user perform unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one,...
