Description

This security bulletin contains information about 1 security vulnerability.


1) Privilege escalation (CVE-ID: CVE-2018-5750)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to a flaw in the acpi_smbus_hc_add() function in 'drivers/acpi/sbshc.c'. A local attacker can submit a specially crafted SBS HC printk system call to obtain potentially sensitive address information and potentially bypass kernel address space layout randomization (KASLR) security protection.
