USN-4116-1: Linux kernel vulnerabilities

It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2018-20856 Amit Klein and Ben...

USN-4114-1: Linux kernel vulnerabilities

Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. CVE-2019-10638 Praveen Pandey discovered that the Linux kernel did not...

FreeBSD : FreeBSD -- Privilege escalation in cd(4) driver (14a3b376-b30a-11e9-a87f-a4badb2f4699)

To implement one particular ioctl, the Linux emulation code used a special interface present in the cd4 driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd4 device t...

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-2019-10142

A flaw was found in the Linux kernel's freescale hypervisor manager implementation, kernel versions 5.0.x up to, excluding 5.0.17. A parameter passed to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the syste...
