The Linux kernel is prone to a local security-bypass vulnerability.
|
|
|
|
A local attacker may be able to exploit this issue to bypass access control and make restricted system calls, which may result in an elevation of privileges.

/* test case for seccomp circumvention on x86-64
|
|
There are two failure modes: compile with -m64 or compile with -m32.
|
|
|
|
The -m64 case is the worst one, because it does "chmod 777 ." (could
|
|
be any chmod call). The -m32 case demonstrates it was able to do
|
|
stat(), which can glean information but not harm anything directly.
|
|
|
|
A buggy kernel will let the test do something, print, and exit 1; a
|
|
fixed kernel will make it exit with SIGKILL before it does anything.
