CVE-2015-5697
Published: 31 August 2015
The get_bitmap_file function in drivers/md/md.c in the Linux kernel before 4.1.6 does not initialize a certain bitmap data structure, which allows local users to obtain sensitive information from kernel memory via a GET_BITMAP_FILE ioctl call.
From the Ubuntu security team
Benjamin Randazzo discovered an information leak in the md (multiple device) driver when the bitmap_info.file is disabled. A local privileged attacker could use this to obtain sensitive information from the kernel.
