CVE-2026-98137: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: ntfs: treat any nonzero dio zero-range return as an error ntfs_dio_zero_range() returns either 0 or a negative errno from blkdev_issue_zeroout(); it never returns a positive value. The zeroing failure check in ntfs_attr_fallocate() therefore never fired, so a failed zeroing operation was silently ignored: the loop kept going, the newly allocated clusters were folded into initialized_size and the write could succeed leaving stale on-disk data. Treat any nonzero return as an error and abort the allocation.

Affected products

• Linux Linux Kernel: from 7.1, before 7.2.7 (fixed in 7.2.7); version 7.3 only
