It also fixes atleast the following security issues:

A Spectre SWAPGS gadget was found in the Linux kernel's implementation of
system interrupts. An attacker with local access could use this information
to reveal private data through a Spectre like side channel (CVE-2019-1125).

A flaw was found in the Linux kernel’s Bluetooth implementation of UART.
An attacker with local access and write permissions to the Bluetooth
hardware could use this flaw to issue a specially crafted ioctl function
call and cause the system to crash (CVE-2019-10207).

It also fixes an issue with newer Intel Wireless cards having firmware
crashes with newer iwlwifi firmwares (mga#25143)
