Description

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.

Affected configurations

• linux linux kernel (< 5.12) • redhat enterprise linux 7.0 • redhat enterprise linux 8.0 • debian debian linux 9.0
