CVE-2026-45985 ext4: don't set EXT4_GET_BLOCKS_CONVERT when splitting before submitting I/O

In the Linux kernel, the following vulnerability has been resolved: ext4: don't set EXT4GETBLOCKSCONVERT when splitting before submitting I/O When allocating blocks during within-EOF DIO and writeback with dioreadnolock enabled, EXT4GETBLOCKSPREIO was set to split an existing large unwritten...

CVE-2026-45985

CVE-2026-45985 affects the Linux kernel/ext4: during within-EOF direct I/O and writeback with dioread_nolock, unwritten extents could be converted incorrectly when splitting before submitting I/O, potentially exposing stale data. Root cause: EXT4_GET_BLOCKS_CONVERT was set during ext4_split_conve...
