Vulnerability Name:

CVE-2014-7825 (CCN-98557)

Assigned:2014-11-07
Published:2014-11-07
Updated:2023-02-13
Summary: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.
