kernel: dm flakey: don't corrupt the zero page

A flaw was found in the Linux kernel's dm-flakey device mapper target. When the corrupt bio writes option is enabled, dm-flakey can corrupt the kernel's global zero page. Since the zero page is shared system-wide and used by glibc's calloc implementation via mmap, corrupting it causes userspace...

kernel: dm flakey: fix a crash with invalid table line

A flaw was identified in the device-mapper “dm flakey” target in the Linux kernel where invalid table line input can lead to a NULL pointer dereference. Specifically, when dmsetup is used with a malformed table line such as with the corruptbiobyte target and the argname pointer is NULL, the kerne...
