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...
CVE-2015-1142857
On multiple SR-IOV cars it is possible for VF's assigned to guests to send ethernet flow control pause frames via the PF. This includes Linux kernel ixgbe driver before commit f079fa005aae08ee0e1bc32699874ff4f02e11c1, the Linux Kernel i40e/i40evf driver before...

UBUNTU-CVE-2017-12190
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...
