CVE-2021-31916

Published: 30 April 2021

An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.

From the Ubuntu Security Team

Dan Carpenter discovered that the block device manager (dm) implementation in the Linux kernel contained a buffer overflow in the ioctl for listing devices. A privileged local attacker could use this to cause a denial of service (system crash).
