Ubuntu 16.04 LTS : Linux kernel vulnerabilities (USN-3753-1)

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3753-1 advisory. It was discovered that the generic SCSI driver in the Linux kernel did not properly enforce permissions on kernel memory access. A local attacker could u...

Kernel: hw: cpu: L1 terminal fault (L1TF)

Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of...

Intel processors’ vulnerabilities, related to the possibility of speculative execution commands, allow attackers to gain unauthorized access to the system memory of the operating system or SMM-memory.

The vulnerability of Intel processors lies in the possibility of speculative execution of instructions. Exploiting this vulnerability can allow an attacker to gain unauthorized access to the memory of the operating system’s kernel or SMM memory by executing attacks through peripheral channels tha...
