Threats tagged 'usn-7861-1'

The Linux kernel contains multiple security vulnerabilities including a flaw known as VMSCAPE, which involves insufficient branch predictor isolation between a guest VM and a userspace hypervisor on certain processors. This flaw could allow an attacker in a guest VM to potentially expose sensitive information from the host OS. Additional vulnerabilities affect the HSI, Bluetooth, and Timer subsystems. These issues could be exploited to compromise the system. Fixed versions addressing these vulnerabilities have been released and are available for update.
