NVD Description

Note: Versions mentioned in the description apply only to the upstream reiserfs-kmp-default package and not the reiserfs-kmp-default package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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.
