CVE-2015-5697: The get_bitmap_file function in drivers/md/md.c in the Linux kernel before 4.1.6 does not initialize a cert...

Security readout for executives and security teams

CVE-2015-5697 is a Linux kernel information leak. A local user could trigger an md driver ioctl and receive data left uninitialized in kernel memory. This is not described as remote code execution, but it can expose sensitive memory on affected systems. Exposure is most likely on Linux systems running kernels before 4.1.6 or vendor kernels without the backported fix. Systems using the md driver or MD RAID functionality are the most relevant. The provided data does not list precise affected distribution package versions. Treat this as a moderate patching priority, higher for shared Linux hosts. The likely business impact is confidentiality exposure from kernel memory, not confirmed system takeover. Address through normal kernel update cycles unless local untrusted access increases urgency. Mitigation focus: Apply the relevant vendor kernel security update for affected Linux distributions.; Upgrade to Linux kernel 4.1.6 or a vendor kernel with the upstream fix backported.; Confirm the kernel includes commit b6878d9e03043695dbf3fa1caa6dfc09db225b16 or equivalent vendor patch..
