kernel: insufficient syscall number validation in perf and ftrace subsystems
Published Nov 10, 2014
7.8
HIGHCVSS 3.1
EPSS 0.59%
Description
kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application.
