Amazon Linux 2 : kernel (ALAS-2018-956) (Dirty COW) (Spectre)

Stack-based out-of-bounds read via vmcall instruction Linux kernel compiled with the KVM virtualization CONFIGKVM support is vulnerable to an out-of-bounds read access issue. It could occur when emulating vmcall instructions invoked by a guest. A guest user/process could use this flaw to disclose...

CVE-2018-7755

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. 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 discove...

CVE-2018-7755

CVE-2018-7755 affects the Linux kernel floppy driver: the fd_locked_ioctl path in drivers/block/floppy.c copies a kernel pointer to user memory in response to FDGETPRM, enabling a local attacker with floppy access to discover kernel code/data locations and bypass KASLR. The issue is in kernel ver...
