EUVD-2026-82122

In the Linux kernel, the following vulnerability has been resolved: ext4: drain in-flight DIO before buffered write fallback generic/746 started failing intermittently on ext3 no-extent inodes. The test triggers 'Page cache invalidation failure on direct I/O' warnings and subsequent fsync returns...

CVE-2026-45892

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs during certain buffered write operations when splitting unwritten data blocks, known as extents. A logic error can lead to an inconsistency where the filesystem's internal record of data blocks the extent status tre...
