Other callers to -__sys_recvmmsg properly copy from userland to the kernel first. - -The bug was introduced by commit ee4fa23c4bfc ("compat: Use -COMPAT_USE_64BIT_TIME in net/compat.c") and should affect all kernels -since 3.4 (and perhaps vendor kernels if they backported x32 support -along with this code). - -Note that CONFIG_X86_X32_ABI gets enabled at build time and only if -CONFIG_X86_X32 is enabled and ld can build x32 executables. - -Other uses of COMPAT_USE_64BIT_TIME seem fine. - -This addresses CVE-2014-0038. - -Signed-off-by: PaX Team <pageexec@freemail.hu> -Signed-off-by: H.
