The packet network protocol implementation in thelinux kernel contained a double-free vulnerability.
The xen subsystem within the linux kernel didnot adequately limit the number of events driver domains (unprivileged pvbackends) could send to other guest vms.
The xen network backend driver in the linuxkernel did not adequately limit the amount of queued packets when a guestdid not process them.
The usb gadget subsystem in the linuxkernel did not properly restrict the size of control requests for certaingadget types, leading to possible out of bounds reads or writes.
Race condition in the unix domain socketimplementation in the linux kernel that could result in a read-after-free.
The xfs file system implementation in thelinux kernel did not calculate size correctly when pre-allocating space insome situations.
The nfc controller interface (nci) implementation inthe linux kernel contained a race condition, leading to a use-after-freevulnerability.
The intel i915 graphics driver inthe linux kernel did not perform a gpu tlb flush in some situations.
The vmware virtual gpu driver in the linux kerneldid not properly handle certain failure conditions, leading to a staleentry in the file descriptor table.
