CVE-2019-15794

Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma-vmfile in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vmfile points. On...

kernel: net-sysfs: *_queue_add_kobject refcount issue

A flaw was found in the way the rxqueueaddkobject and netdevqueueaddkobject functions in the Linux kernel handled refcounting of certain objects. This flaw allows a local user who can trigger the error code path to use this vulnerability to disturb the integrity of the system...

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...
