kernel: Information exposure in fd_locked_ioctl function in drivers/block/floppy.c

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location ...

CVE-2019-6492

CVE-2019-6492 affects IObit Smart Defrag 6, specifically SmartDefragDriver.sys (version 2.0). The issue: a kernel-pool allocation made with user-defined bytes/size via IOCTL 0x9C401CC4 is never freed, allowing a kernel-pointer leak if the pool grows large. This description is supported by Red Hat...
