CVE-2026-63812 f2fs: fix incorrect FI_NO_EXTENT handling in __destroy_extent_node()

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix incorrect FINOEXTENT handling in destroyextentnode When destroyextentnode sets the inode flag FINOEXTENT, it does not reset the length of the largest extent to 0 and update the inode folio. Since modifications to the...

CVE-2026-63812

The CVE describes a Linux kernel f2fs bug: when __destroy_extent_node() sets the inode flag FI_NO_EXTENT, it fails to reset the length of the largest extent and update the inode folio, causing a stale cached extent and an error seen in xfstests generic/388. The issue arises in the f2fs_drop_inode...

CVE-2026-63811

Summary of CVE-2026-63811 (Linux kernel, f2fs) : A defect in atomic writes for F2FS can cause a mismatch between the cryptographic context used for decrypted reads and the actual on-disk data, due to how the COW inode and original inode are chosen for page reads. The read path may decrypt data us...
