Last modified

CVE-2014-9419 is a vulnerability of currently unknown severity. The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
