nbd input validation error vulnerability

nbd is a tool for Linux kernel network block devices. It is used to use remote block devices over TCP/IP networks. nbd versions prior to 3.24 have an input validation error vulnerability in nbd-server, which stems from an integer overflow in nbd-server, resulting in a heap-based buffer overflow...

kernel: incomplete permission checking for access to rbd devices

A flaw was found in the capabilities check of the rados block device functionality in the Linux kernel. Incorrect capability checks could alllow a local user with root priviledges but no capabilities to add or remove Rados Block Devices from the system...

libblockdev bug fix and enhancement update

The libblockdev packages provide a C library with GObject introspection support used for low-level operations on block devices. The library serves as a thin wrapper around plug-ins for specific functionality, such as LVM, Btrfs, LUKS, or MD RAID. Bug Fixes and Enhancements: libblockdev doesn't ru...

A Logical Volume Manager / LVM primer for Linux

About LVM LVM is an abstraction layer that provides block devices same kind of disk partitions. This is done by using 3 layers: physical volumes PV - disk partitions; volume groups VG - aggregates of physical volumes, could be across multiple disks or multiple partitions, whatever; logical volume...

kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS

A flaw was found in the Linux kernel’s implementation of biovecs. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device,...

Privilege Escalation

linux-kvm is vulnerable to privilege escalation. The vulnerability exists as the rbd block device driver in drivers/block/rbd.c used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices...

Important: kernel

Issue Overview: A flaw was found in the Linux kernel. When changing screen size, an out-of-bounds memory write can occur leading to memory corruption or a denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. CVE-2020-14390 A flaw was found in the...
