Package: src:linux Version: 4.16.16-2 Severity: important Dear Maintainer, starting X via 'startx' causes every screen to stay black, no more interaction with mouse or keyboards is possible. So I connected via ssh and tried to execute 'systemctl reboot'. Only the ssh connection was closed but the system stayed running without any interaction. After a reboot I looked again via ssh what dmesg prints out. It said "usercopy: Kernel memory exposure attempt detected from SLUB object 'nvidia_stack_cache' (offset: 11440, size 3)!", followed by the message mentioned in the subject. Therefore the system is not usable with X in this configuration. nvidia-driver is in version 390.67-1 -- Package-specific info: ** Version: Linux version 4.16.0-2-amd64 (debian-ker...@lists.debian.org) (gcc version 7.3.0 (Debian 7.3.0-23)) #1 SMP Debian 4.16.16-2 (2018-06-22) ** Command line: BOOT_IMAGE=/vmlinuz-4.16.0-2-amd64 root=/dev/mapper/loki-root ro cgroup_enable=memory swapaccount=1 quiet ** Tainted: PDO (4225) * Proprietary module has been loaded. * Kernel has oopsed before. * Out-of-tree module has been loaded. ** Kernel log: [ 116.932901] ? _nv028088rm+0x55/0x90 [nvidia] [ 116.933048] ? _nv013695rm+0xee/0x100 [nvidia] [ 116.933195] ? _nv015343rm+0x154/0x270 [nvidia] [ 116.933350] ? _nv008317rm+0x134/0x1a0 [nvidia] [ 116.933505] ? _nv008296rm+0x29c/0x2b0 [nvidia] [ 116.933661] ? _nv001072rm+0xe/0x20 [nvidia] [ 116.933818] ? _nv007324rm+0xd8/0x100 [nvidia] [ 116.933962] ? _nv001171rm+0x627/0x830 [nvidia] [ 116.934106] ? rm_ioctl+0x73/0x100 [nvidia] [ 116.934240] ? nvidia_ioctl+0xb0/0x730 [nvidia] [ 116.934370] ? nvidia_ioctl+0x57c/0x730 [nvidia] [ 116.934371] ? kmem_cache_free+0x19c/0x1d0 [ 116.934501] ? nvidia_frontend_unlocked_ioctl+0x3e/0x50 [nvidia] [ 116.934502] ? do_vfs_ioctl+0xa4/0x630 [ 116.934504] ? __fput+0x164/0x1e0 [ 116.934505] ?
