CVE-2016-9178: The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not ini...

Security readout for executives and security teams

This is a Linux kernel information leak fixed in kernel 4.7.5. A local user could cause a failed user-memory access path and receive data left on the kernel stack. It is not described as remote code execution or privilege escalation by the supplied sources. Exposure is limited to systems running vulnerable Linux kernel code before 4.7.5, or vendor kernels without the relevant backport. Risk is higher where untrusted local users or workloads can execute code on the host. Treat as a routine but real kernel information disclosure issue. Prioritize multi-user and shared workload systems, but current source evidence does not support emergency response for internet-wide exploitation. Mitigation focus: Upgrade to Linux kernel 4.7.5 or a vendor kernel containing the fix.; Check Linux distribution advisories for backported fixes before assuming version numbers are sufficient.; Prioritize shared systems with untrusted local users or workloads..
