Description
A race condition was found in the way the Linux kernel's memory subsystem
handled the copy-on-write (COW) breakage of private read-only memory mappings.
An unprivileged, local user could use this flaw to gain write access to
otherwise read-only memory mappings and thus increase their privileges on the
system. (CVE-2016-5195, Important)
* Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual
eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet
Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could
occur while receiving large packets via GRO path; As an unlimited recursion
could unfold in both VLAN and TEB modules, leading to a stack corruption in the
kernel. (CVE-2016-7039, Important)
