The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before
11
3.13.2, when CONFIG_X86_X32 is enabled, allows local users to gain
12
privileges via a recvmmsg system call with a crafted timeout pointer
15
Pageexec reported a bug in the Linux kernel's recvmmsg syscall when called
16
from code using the x32 ABI. An unprivileged local user could exploit this
17
flaw to cause a denial of service (system crash) or gain administrator
20
jj> x32 abi enabled kernels only: CONFIG_X86_X32 && ld can build x32
