Last modified

CVE-2014-8133 is a vulnerability of currently unknown severity. arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in the Linux kernel through 3.18.1 allows local users to bypass the espfix protection mechanism, and consequently makes it easier for local users to bypass the ASLR protection mechanism, via a crafted application that makes a set_thread_area system call and later reads a 16-bit value.. EPSS estimates a 0.58% chance of exploitation in the next 30 days.
