Moderate Race Condition Detected in Scientific Linux SL7.x Kernel Update

It was found that the timer functionality in the Linux kernel ALSA subsystem is prone to a race condition between read and ioctl system call handlers, resulting in an uninitialized memory disclosure to user space. A local user could use this flaw to read information belonging to other users. (CVE-2017-1000380, Moderate) SL7 x86_64 kernel-3.10.0-693.11.1.el7.x86_64.rpm kernel-debug-3 [More...]
