CVE-2026-89614

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol-lcnemptybitsperpage is sized from vol-nrclusters at mount, but ntfsclusteralloc bounds its scan of that array by the size of $Bitmap. Those are independent on-disk...

CVE-2026-89614

CVE-2026-89614 affects the Linux kernel's NTFS file system driver . The flaw is in ntfs_cluster_alloc(), which bounds its free-cluster bitmap scan by the size of the on-disk $Bitmap rather than by the volume's actual cluster count (nr_clusters). Because these are independent quantities, a special...

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol-lcn empty bits per page is sized from vol-nr clusters at mount, but ntfs cluster alloc bounds its scan of that array by the size of $Bitmap. Those are independent on-disk...

CVE-2026-72187

In the Linux kernel, the following vulnerability has been resolved: ntfs: avoid self-deadlock during inode eviction An attribute-list update performed while allocating clusters can drop the last reference to the temporary attribute inode. Evicting that inode drops its reference to the base inode...

CVE-2026-72164

CVE-2026-72164: Linux kernel OCFS2 fix for moving extents to occupied clusters. The issue occurred during non-auto OCFS2_IOC_MOVE_EXT: a probe could leave a caller-controlled goal unchanged or misreport free runs, allowing data to be written into a cluster still owned by another inode. The patch ...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from unverified allocation of cluster allocation bits of the bitmap, which could lead to data corruption...
