Summary
This kernel update is based on the upstream 4.14.137 and 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 that allowed an attacker to corrupt memory and possibly escalate
privileges was found in the mwifiex kernel module while connecting to a
malicious wireless network (CVE-2019-3846).
An infinite loop issue was found in the vhost_net kernel module in Linux
Kernel up to and including v5.1-rc6, while handling incoming packets in
handle_rx(). It could occur if one end sends packets faster than the other
end can process them. A guest user, maybe remote one, could use this flaw
to stall the vhost_net kernel thread, resulting in a DoS scenario
(CVE-2019-3900).
A flaw was found in the Linux kernel’s Bluetooth implementation of UART.
An attacker with local acce...
