CVE-2026-89614

A flaw was found in the Linux kernel's NTFS file system driver. This vulnerability occurs because the free-cluster bitmap scan is not properly bounded to the volume size. A specially crafted NTFS image, where the bitmap covers more clusters than the volume actually has, can lead to an out-of-boun...

CVE-2026-89558

A flaw was found in the Linux kernel's md/raid10 RAID10 driver. This vulnerability occurs when a RAID10 array is in a degraded state and a device is being recovered while another mirror is still missing. Due to an inverted boolean value, the system incorrectly clears necessary bitmap bits, causin...
