Last modified
CVE-2014-7825 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of-bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application.. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
