The vulnerability of the ublk_ctrl_end_recovery() function in the drivers/block/ublk_drv.c module of the Linux kernel’s block devices driver allows a attacker to cause a service failure.

The vulnerability of the ublkctrlendrecovery function in the drivers/block/ublkdrv.c module of the Linux kernel’s block devices driver is related to the improper shutdown or release of resources. Exploiting this vulnerability could allow an attacker to cause service failures...

QEMU: block: iscsi: OOB heap access via an unexpected response of iSCSI Server

An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU handled a response coming from an iSCSI server while checking the status of a Logical Address Block LBA in an iscsicoblockstatus routine. A remote user could use this flaw to crash the QEMU process,...

kernel: Use-after-free in __blk_drain_queue() function in block/blk-core.c

A flaw was found in the Linux kernel’s block driver implementation blkdrainqueue function where a use-after-free condition could be triggered while draining the outstanding command queue in the systems block device subsystem. An attacker could use this flaw to crash the system or corrupt local...
