CVE-2026-90322
CVE-2026-90322 affects the Linux kernel OCFS2 cluster subsystem (nodemanager and disk heartbeat). The root cause is that when the local node is reset via local=0, the cl_has_local flag is left set while cl_local_node is set to the invalid value 255. Heartbeat threads that dynamically re-read o2nm...
EUVD-2026-81983
In the Linux kernel, the following vulnerability has been resolved: ocfs2/cluster: keep heartbeat local node stable o2nmnodelocalstore handles local=0 by stopping o2net and setting cllocalnode to O2NMINVALIDNODENUM, but it leaves clhaslocal set. That stale state makes o2nmthisnode return 255,...
CVE-2026-89491
A flaw was found in the Linux kernel's ocfs2 cluster module. This vulnerability allows a local attacker to trigger a denial of service. The issue arises when a sleeping function is called while a spinlock is held within the o2hbregionpin function, which can lead to a system crash or deadlock. Thi...

The vulnerability of the OCFS2 cluster file system in Linux kernel allows a hacker to execute arbitrary code or cause a service failure.
The vulnerability of the OCFS2 cluster file system in Linux operating systems relates to operations that go beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to execute arbitrary code or cause service failures...
