## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> The Linux kernel's ocfs2 cluster code is affected from 2.6.16 until the fixes listed for each stable branch. Clearing the local node through configfs can leave heartbeat threads reading an invalid node number, which causes an out-of-bounds memory read. The source does not say what access an attacker needs or what else they could do. Upgrade to 6.1.191, 6.6.160, 6.12.110, or 6.18.52 or later in those series.
