Diamorphine Rootkit Signal Privilege Escalation
Posted Feb 20, 2020
Authored by m0nad, Brendan Coles | Site metasploit.com

This Metasploit module uses Diamorphine rootkit's privesc feature using signal 64 to elevate the privileges of arbitrary processes to UID 0 (root). This module has been tested successfully with Diamorphine from master branch (2019-10-04) on Linux Mint 19 kernel 4.15.0-20-generic (x64).

Kernel Live Patch Security Notice LSN-0063-1
Posted Feb 20, 2020
Authored by Benjamin M. Romer

Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
