Detailed vulnerability description
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.
