QID 198665: Ubuntu Security Notification for Linux kernel (HWE) Vulnerabilities (USN-5295-1)

The packet network protocol implementation in thelinux kernel contained a double-free vulnerability.
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 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.
