https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D232920 Bug ID: 232920 Summary: linuxulator: linux_to_bsd_sockaddr and bsd_to_linux_sockaddr are unsafe Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: brooks@FreeBSD.org The bsd_to_linux_sockaddr() and linux_to_bsd_sockaddr() functions alter the userspace sockaddr to convert the format between linux and BSD versions. If the sockaddr is shared between concurrent syscalls or the pages are unwrita= ble these functions will fail. Code should either be altered to perform the transformation purely in the kernel or at a minimum, copyout_map should be used to allocated a new locat= ion for the transformed sockaddr. --=20 You are receiving this mail because: You are the assignee for the bug.=
