CVE-2026-72159

A flaw was found in the OCFS2 file system within the Linux kernel. This vulnerability occurs when processing specially crafted file system metadata, specifically non-inline dinodes that report a non-zero file size but zero allocated clusters. An attacker could potentially create a malformed file...

CVE-2026-72164

A flaw was found in the ocfs2 component of the Linux kernel. A local user can exploit a vulnerability in the ocfs2moveextent function when performing OCFS2IOCMOVEEXT operations. This issue allows file data to be copied into a disk cluster that is already occupied by another file, leading to data...

CVE-2026-72162

A flaw was found in ocfs2, a component of the Linux kernel. On-disk corruption of an inode's embedded extent list can lead to an array-index-out-of-bounds error. This occurs when the lnextfreerec value is zero or exceeds lcount during a write operation to the affected file. A local attacker with...

CVE-2026-72161

A flaw was found in the ocfs2 component of the Linux kernel. A local user could trigger a NULL pointer dereference during the unmount process of an ocfs2 filesystem. This occurs because the system attempts to access a freed journal pointer, leading to a system crash and a Denial of Service DoS...

CVE-2026-72160

A flaw was found in ocfs2 Oracle Cluster File System version 2 in the Linux kernel. This vulnerability arises from insufficient validation of on-disk inode metadata, specifically the imode type bits. A local attacker could exploit this by crafting a malformed disk inode with a non-canonical POSIX...
