Out-of-bounds write in Linux kernel - CVE-2021-31916

Vulnerability identifier: #VU63574

CSH Severity: Low

CVSS v4 BT: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-31916

CWE-ID: CWE-787

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module. A special user (CAP_SYS_ADMIN) can trigger a buffer overflow in the ioctl for listing devices and escalate privileges on the system.
